I feel you on that. I loathed the Rat before ever playing one. Wrote it off as an 80's hair metal distortion or something and didn't want anything to do with one. Somewhere along the way, I decided to build one for a friend as a gift. 5 years later the friend never received the Rat and it...

This is a common complaint with the Westwood. The lack of tone-shaping in the clipping section was supposed to be a feature and not a bug, but a lot of people, myself included, find it too stingy even with the active Treble control turned all the way down. Turn 'Gain' to zero and set Bass and...

Does anyone have the predrill values for a Terrarium? Will Tayda do the side hole for the Micro-USB plug?

You need some trickle of of current going through the base-emitter junction of a BJT or the transistor won't turn on. 2m2 is a super common value. The circuit looks like an implementation of a James tone stack using a BJT transistor as the active component / amplifier. Compare to this...

Exactly. You could use 1 alligator clip to connect the points together, or 2 alligator clips to connect them across a momentary switch. If you like the result, replace the alligator clips with wires. I had this PedalPCB board mixed up with another EQD Delay. I actually do have this pedal on my...

Do you have the PCB built? You could test this using alligator clips. Connect Lug 3 of the Repeat pot with Lug 3 of the Level pot.

Connect the green mesh and the blue mesh. I've never built this circuit, but if it's capable of getting into oscillation with the 'Repeat' knob maxed out, this will do the trick. If not, we'll figure something else out.

Ah yeah. That's what I was guessing. After trying a Blue Box and some of the Parasit Studio circuits I decided I liked clean analog octave into distortion more than the square wave octave down. By pairing an OC-2, POG, UBoat, U235 or similar with a distortion pedal, you can get cool roots rock...

Are you a bassist? I too love Octave Down circuits and had a long period of obsession with them, but as a guitarist, I never found a very useful application.

Now I wonder if the J Rockett Mark Sampson Max is another 2-knob Klon too. It has the same control layout as the Lenny. I was considering buying one to trace it, but I'd hate to put that time investment into it just to find out it's another modded Klon.

So it's a Dumble in a box now too.🤦‍♂️

If anyone actually read this, yes the Clean should clip on it's own when the Color control is maxed and you dig into the strings, but just a little bit.

Old thread, but I'm trying to understand this one too. Comparing the build guides (KlicheMini, KlicheBoost), I spot a few very minor differences between the boards. The spacing of D1 / D2 to accommodate for Ge vs Si diodes. The dual-ganged pot label 'Drive' replaced with 'Color' R9 marked for...

Now I've got to build one. Since I started using Vox amps I haven't liked fuzzes, but this one is an interesting crossover with an original topology. I can't say I'm blown away when listening to Youtube demos, but the guitarist demoing it always seems to be in a state of bliss. When the boards...

The parasitic capacitance is actually at the Collector-Base Junction of the transistor, from what I understand. It allows high-frequencies to pass back into the Base, creating Negative Feedback and thereby only attenuating Treble. The effect increases with gain due to some physics at the...

Probably. I don't know enough to tell whether Q2 is inverting or not. If it's non-inverting then there would be a negative feedback path. So in the High-Gain position, the negative feedback path would be (mostly) eliminated, and the Q1 Emitter would be (mostly) grounded, both bumping the Q1...

I believe that's true. Someone more knowledgeable can correct me if I'm wrong, but I recall that the Miller effect increases with Gain. When people take Germanium Fuzz designs and convert them to Silicon they often put a small cap across the Base and Collector to mimic the capacitance /...

R14 would be a good candidate. Something like: Replace R14 with 10k trimpot Trimpot wiper goes to 10n cap 10n cap goes to ground Optional: replace R15 with 21k resistor to maintain similar output volume.

Now I'm tempted to build one. I'm reading claims online that as gain is turned up, the treble is cut. I am doubtful of this, but I think I heard someone at DIYSB once say that parasitic capacitance (ie miller effect) goes up as gain is increased. Looking at the schematic, I'm struggling to...

I'm the opposite. I keep liking the 'too bright' gear, which makes me think I might have some high-frequency hearing loss. So a treble-bleed cap but the opposite. What size cap are you thinking? 2n2 or so?
