You should try the Gorva M45 if you haven't - it's just a little larger than the 1590A but designed so you can squeeze in top jacks including a power jack: Nice builds geoffrey. The Colorsound One Knob Fuzz is one of my favs - hard to beat for a one-knobber IMO.

Yes, when it's not bypassed, increasing the emitter resistor with no other changes will increase the input impedance, amp linearity, and bias stabilization for varying transistor specs, but it will decrease voltage gain. It will also raise the collector voltage, so it's probably wise to also...

Yes it's definitely true of the Rangemaster as well. Basically, anything with a common emitter stage (input to base, output from collector) at the input will have a fairly low input impedance if it does not have an emitter resistor (e.g. Fuzz Face, Tonebender Mk2, Fuzzrite, etc.) or if it has...

It'll work without trouble. BC338 without a suffix is just a non-hfe-selected version. If that's what was in originals (which seems to be the case), they may have been anywhere in the 100-630 hfe range so any of those should work just fine.

Here's a Mini Dunlop FF rebuild I did using an After Dark board:

Nice, glad you got it going. That's correct - the original was wired "backwards" from what you'd normally do. When the pots are mounted on the top/back rather than the face of the enclosure, the intuitive way to turn the control "up" is turning the knob to the right, which is actually a...

Hi ChunkyKarma, the Fuzzrite board mounts to the case via the DPDT so using something else is tricky. The footswitch wiring on the Fuzzrite is particularly odd as well. I THINK that you should be able to do it with a minor tweak, but you should probably test this before soldering anything...

I'm repeating some of what has already been stated here, but to be able to connect them in whatever order you'd like, pedals should ideally be designed with high input impedance, and modern ones pretty much always are. Having a low input impedance loads the previous stage more. Low output...

Agree that they're most likely custom. They're made of folded sheet metal. I think sites like Ponoko will do custom designs in very small quantities (1?) but it's probably very expensive there. Some people buy a bending brake and attempt it at home with aluminum sheets, although depending on...

That's a great look for Remi! Here's Josie. She has watched me build too many pedals and she is no longer impressed.

NKT222 was used in certain Tonebender Mk3 builds, so that's cool. There does seem to be a lack of online info about this type. In addition to the equivalents listed above, other 2GT types (2GT102) are listed as a European type here (pg 134): https://archive.org/details/transistor-equivalents...

What is it soldered to that's holding it in there? Just the power jack? I'd remove the pot hardware so the pots can just come right out and probably leave the wires connected to the board and see if there's enough slack in the wiring to flip the board over without de-soldering anything else. You...

Big fan of Fripp and Eno in general but they made some real magic here IMO.

No problem! Also FYI - 2N4061s (used in originals) had a datasheet hfe range from 90-450 hfe from what I can tell, whereas the BC109C starts at 450 hfe minimum (450-900). The 2N3906s (2N3904 if NPN) have a lot more crossover with 2N4061s (100-300). I'd think you should be able to get those...

Note that although the circuit looks like a FF at first glance, the fact that it's lacking the global feedback (through the 100K resistor in the FF) is noteworthy. Q1 is biased with local collector feedback instead. Also, there is typically a pulldown resistor (470k) at the input although...

Thanks for the input! We will definitely consider an FY2 board. The Buzzaround always used the same style of terminal board, didn't it? We have a style that I believe is a pretty good match for that: P-HTBU-2X18 Unfortunately, this one is larger at 2x18 lugs. It's not ideal, but I've cut this...

Absolutely. Actually, just today we added a couple of items which may be of interest: Tonebender MkII board This is vintage-spacing stripboard pre-cut to Tonebender MkII size with the copper cuts and mounting holes already made. There's an example layout in the photos as well as a diagram for...

That's great to hear! We sold out of that initial batch insanely quick but we should have a larger order arriving either tomorrow or Thursday, along with a version that has black solder mask and a gold surface finish which I personally think looks excellent. Here's another side by side pic of...

Old thread, but since I came across this on google and Cricklewood is still selling these, I wanted to let everyone know that there's some concern that these are fake. The printing/general look on these is a lot closer than most fakes you see. The biggest indicators that have been pointed out...

Great question. Let me see what I can do! Shoot me an email if you (or anyone else!) want updates but this is a great suggestion. If we can make it happen we will.
