ZIM is like two separate pedals joined at the hip. The two channels can be configured a number of different ways, depending on which ZIM Cards are installed. The convenient arrangement allows you to easily customize your ZIM to suit your needs. Unless otherwise specified, ZIMs come with the default Overdrive cards.
ZIM is not the same as other overdrives. Instead of a bypass switch and a boost switch, ZIM has two individual channels which can be used individually or together in series (cascaded). Each has its own true bypass (3pdt) switch with LED. This gives you three different sounds (A, B, or A + B). With the option of having two gain stages in series, you"ll never be starved for gain.
Instead of a treble control, ZIM has a unique voicing circuit that gives you almost limitless control of your overdriven tone. In addition, each channel has its own bass/treble trimmer which can be set internally.

ZIM Card Swap If you"ve researched ZIM and have gotten this far, then you understand that ZIM"s two channels use plug-in cards for their processing. Any card can go into either slot, and any combination can be tried. This gives you the ultimate flexibility for configuring your own ZIM! It also allows you to justify having multiple ZIMs, putting out completely different sounds.
When you order ZIM, it comes with a pair of ZIMcards already installed. The current default ZIMcards are Vintage Tube in Channel A and Hot 9 in Channel B. This pair gives a wide range of overdrive sounds, Channel A (VT) is a clean, transparent OD with plenty of headroom and a natural voicing that sounds great with a strat. Channel B (H9) is great for dirtier, grittier sounds. And the two channels cascaded are great for lead work.
Card Swap Want to try other combinations? If you don"t mind being without a channel in your ZIM for a week or two, you can send a ZIMcard in for a card swap. Or, you can purchase spare ZIMcards. If you find yourself with spare ZIMcards that don"t get any use, we offer a buy-back arrangement so that they don"t go to waste. You can also get a discount on a ZIM without ZIMcards installed. You can download the ZIM Card Swap form by clicking on the link in the sidebar.
Open your ZIM and take note of what ZIMcards are installed. Look at what"s available and decide what you want to swap out. Print out the document and fill it out. Remove the card, pack it up, include the form and send it in. There it is - it"s quick, easy, painless, and inexpensive to totally change the sound of your ZIM. You can swap to your hearts content...you can even ask about special mods to make ZIM fit your needs whatever they might be.
ZIMcard purchase If you"d like to purchase extra ZIMcards, the price across the board is 55,00 € including shipping both domestic and export.
B9 Big 9 - Modified Tube Screamer A "boutique" Tube screamer, if you will. More bass and more available gain range (.1uf / 3.3k, 1 meg gain pot w/ 10K series). Mid-hump is softened resulting in a more up-front sound. The clipping diodes include a 1N270 Germanium to make the clipping slightly asymmetrical.
The circuit mods are the same as other successful TS clones and common upgrades. If you like the sound of other "boutique" TS clones, and want that sound in your ZIM, B9 is the way to go. With the voicing section in Ch B, and the ability to be driven harder by Ch A, B9 will give you what you always wanted from that boutique overdrive.
VT Vintage Tube VT is currently the default for Channel A. A super clean overdrive with soft clipping and mild compression as the gain knob is increased. Perfect for fattening up a thin clean tone or pushing another Overdrive for added gain and sustain. Voiced to make a strat sound more "stratty".. The gain knob and/or your guitar"s volume knob will take you from a very warm clean tone to moderate saturation, never masking the sound of your pickups. A mild tube-like compression is always there making VT perfect for warming up your clean tone, especially if you use a solid state amp. VT is very similar to CS, but with a slightly different voicing and more headroom. If you want a transparent overdrive and CS doesn"t quite do it for you, you should try VT.
T-9 TS-9 Clone If you love the sound of a stock TS-9, and want that sound in your ZIM, T-9 is the way to go. Same tone, gain, low cut, mid hump, ect.... same sound. This is the classic tone that everyone seemed happy with before modifications became the norm. All stock values are intact.
H9 Hot 9 - Modified TS H9 is currently the default for Channel B. A very high-fidelity and high-gain version of the TS circuit. Full bass, even mids, smooth top end. At low gain it"s a great overdrive and at high gain it"s in distortion territory. Double diode configuration in the clipping section enhances sonic clarity and low mids. Basically H9 delivers the gain of a distortion with the voicing of an overdrive.
CS Clean Smile - Transparent Overdrive A very transparent, tube-like overdrive that lets the sound of your pickups shine through. Mild crunch with clean bass and treble and no mid hump. Also works well as a moderate gain clean boost. Cleans up well with your guitar"s volume knob. Feel the thump of the low E string, and hear fingers rub against the high strings.. all of your sound comes through. Very similar to VT, but with more inherent gain and a slightly different voicing. If you want a transparent overdrive and VT doesn"t quite do it for you, you should try CS.
BB Buffer Boost A buffer/boost with adjustable tone color and slight saturation. The DRIVE knob takes you from a warm, slightly dark boost at the lowest setting, to a full-range clean boost around the middle settings, to a bright saturated boost when maxed out. BB can serve as a buffer, a booster, a tone control, and can add more break up to whatever is before or after it. It can also serve as a great clean buffer for your pedal board.
BB as a buffer - If you set up BB as just a buffer, you"ll enjoy added clarity when comparing the buffered signal to the bypassed signal. It"s amazing how much signal loss there is in even short amounts of cable. To run as a buffer, you turn the volume up to max and leave the drive down. Then, increase the drive to where you like it.
BB as a volume boost/cut - You might want to set up a ZIM channel for a volume boost or cut. For this, install BB in Ch A and use the patching jacks to swap the order of effects - go into B first, and then into A.
BB as an EQ / Notch filter - You can use BB to change the color of whatever sound you already have. For this, install BB in Ch B and use B"s Voice and Depth controls to alter the sound. This is best when after any ovedrive/dist/fuzz effects, but you can also get some neat sounds by doing it the other way around.
BB as a gain boost or overdrive - Not recommended. There are other ZIMcards that are much better for this kind of thing. VT is probably the place to start for a nice gain boost, and H9 will take you to the edge of OD, delving into distortion territory.
T+ TAR + Vintage Metal Distortion A tweaked version of the classic distortion circuitry used in Distortion +, Rat, and other distortion pedals. Nice 70"s/80"s style crunch with plenty of gain and output volume. Think Judas Priest, Scorpions, Maiden, Dio, Metallica.. TAR+ digs deep into the bowels of old school heavy metal and pulls out a prime turd machine just for you.
T+ works well with BB by setting up BB as a post-distortion volume boost. T+ has plenty of gain on it"s own, so ZIM"s other channel can be used to boost leads.
You can set it up with T+ in A, and BB in B. A alone will be your basic distortion tone and switch in B for a volume boost and a change in voicing.
Or, try it with T+ in B and BB in A and swap order. Run A after B by going into B and patching the output of B into the input of A, and output of A to amp. This way, you can use B for your distortion tone with a voicing, and kick in A for a straight volume boost.
There are lots of ways to hook things up, but since T+ is a distortion, with a lot of available gain, it"s not recommended that you pair it up with other high gain effects unless you plan on NOT cascading them. You can only apply so much gain until things start to feedback and create noise.
BM Brown Muff - Fuzz/Distortion A great lead tone that falls somewhere in between Fuzz and distortion, this is ZIM"s take on the Big Muff Pi. This is a modified version of the transistor muff. Silky smooth sustain and classic tone.
FF Fat Fuzz - Vintage Fuzz A new take on the vintage Dallas Arbiter circuit. A stable circuit that delivers the same fat attack and organic sustain of the classic Fuzz Face. Finally you can have a Fuzz that truly cuts through. Apply a Voice to Fat Fuzz and your Jimi leads will never be buried again. It includes a light overdrive stage which smooths out the sound. You won"t get that "ice pick" sound that can happen when using a Fuzz through a clean amp.
Circuit description - In order to put a FuzzFace circuit into ZIM, I had to change a couple of things. This is due to the values of the DRIVE and VOLUME controls. The Fat Fuzz ZIMcard consists of a medium gain Silicon NPN FuzzFace circuit followed by a mild overdrive stage and a tone control. The overdrive stage smooths out the tone and provides additional gain and clipping when the DRIVE knob is turned up. The tone control is on a blue trimmer.
On the input side, all the rules that apply to a FuzzFace also apply to the FF ZIMcard. This means that you should avoid putting buffered effects before the Fat Fuzz, it will kill the authentic tone and create a lot of noise. Like a FuzzFace, the Fat Fuzz input wants to see your guitar pickups only. This way you can use your guitar volume knob to get an almost clean sound. Also, most wah pedals will interact just like they do with a FuzzFace - narrow range and oscillation. To learn more about this, look at the Foxrox Wah Retrofit.
