Keeler Kick
After the heads up from Miro, here’s the sites 200th fuzz layout! :o) The original has a 5K trimmer in between Texture 1 & 2 and the collector of Q3 which I have omitted to keep this 1590B friendly in terms of number of columns. I think a trimmer there is largely unnecessary as it … Read more
Ibanez TS9DX Turbo Tube Screamer
This puppy is basically another TS9, but it has clipping and gain options on “mode” switch. Modes are TS9, +, Hot and Turbo. Latter one acts as a diode lift, but adds a lot of gain. The switch is 2P4T rotary. Original unit has 250K dual gang pot for gain, and for some reason it … Read more
Ibanez TS5 Tube Screamer
Hehee! Couldn’t help myself. It is in reality a TS9 🙂 If you want it 1:1, then use TA75558 and 2SC1815 transistors (mind the pinout!). You could of course build it with JRC4558D and check the output resistors to make it 808.. I still thought we needed at least one more Soundtank to our library. … Read more
NPN Si Tonebender MKII
This one’s for those who had trouble with the Ge layouts. It adds Orman’s and Tremblay’s mods to the classic and it is supposed to sound like the real thing. If you want, you could swap the 5K6 resistor for 10 trimmer or even take it off board to act as a bias control. Transistors … Read more
Mindbender Fuzz – Mojo layout
Really useful mods for the all-time classic, the Tone Bender MKII Professional. Mods add more volume and a trimmer for accurate biasing the germs among other things… From Fuzzcentral: Here is my modified version of the ToneBender MKII Professional, the MindBender. I decided to use NPN Germanium transistors for mine so that I’ll be able … Read more
Mindbender Fuzz – Compact layout
Same as the Mojo version, but with smaller board, made to accomodate your standard components. Description on the Mojo version post.
EHX Pulsar
Here’s the original ’79 two knob version of the EHX Tremolo…. Here’s a modded layout that may cure the reported LFO clock bleed. Note that the semi-transparent 47µ cap is there just as an example. You should probably try different values there to find out what works the best. Also the 470R resistor should be … Read more
G2D Cream Tone
I used a quad opamp to keep the size down, so this should fit in a 1590B. Solo Switch is a second stomp to give you a volume boost when soloing (funnily enough) and only a SPDT stomp is required for this, but use a DPDT if you want LED indication showing the “channel” you … Read more
Pink Jimi Photon’s Transmission OD
Incorporating couple of cool ideas, here’ one from the man, Pink Jimi Photon. Note that the master volume control is optional and anything smaller than 1M will probably hurt the output level. The level should be within reasonable limits without it. Here’s the original description: Positive it’s been done a gazillion times before. but one … Read more
