It's not called a Tour Bender because its built to be tour rugged, it's called that as a play on the 60's fuzz called the Tone Bender, which is what this pedal circuit is approximating with silicon transistors as opposed to the original's germanium, and for obvious trademark reasons they can't call it a Tone Bender, but the name alludes to historic pedal name/circuit type.
Attaching leads to the top of the PCB is a pretty old-school way to do things. I don't understand the preference either, but most of the 80s-era Japanese pedals I've worked on do it that way. Maybe it's easier to install the leads using a jig and a hot plate?
Hi Joe , really top channel! What are the values for Q1; Q2; Q3? Would be Great to get the analysis of the Great eastern focus fuzz , also top Notch designed pedal.
@@luclou8636 I'm not planning on pulling the t ransistors to test for gain, but if you're building your own I would start with TB Mk I values and go from there.
I've come across a ton of old electronics built this way with lay down flooded connections...seems they are going for a vintage look...wouldn't be my choice at all but I understand why they're doing it...think the last thing I had was an old war ship radio that had it
I love these videos! It would be really cool to see the Walrus Eons, EAE Longsword, or the 29 Pedals FLWR.
Awesome video!
I love their pedals! A friend of mine works there building pedals. I'll ask him why they solder the wires onto the face of the pad.
Knowing the size enclosure, one could get a replacement bottom plate to attach hook and loop to.
Very true!

Hmm, I just happen to have pulled a ton of 2n2907a transistors from some old PCBs...
Those pots are weird man. Beautiful pedal though
GRAY BENCH, Why do you need extra DC filtering for PNP transistors and Positive ground?
pots look high quality. brass shafts. Alps?
Kittycasterfx groovy wizard please!

Yeah I came to the same conclusion, it's just for ease of assembly.

Thanks! Values in terms of part number? 2N2907A for all three.
@@graybenchelec Hi Joe, was eager to know the hfe values.

Solder is NOT a mechanical hold. ALWAYS use the through hole with wire.
@@return2sender791 IPC manual look it up.
yeah, it seems like a cheap-out in this pedal
It’s akin to using tape as a mechanical hold, don’t do it.

It's the same as SMD. It's fine.
Would it be kind of like a boosted mk1 Bender? I think the first stage of a mk1 is a buffer, where this has an amp stage
It's probably the closest to a Mk I yes, but still noticeably different.
Is there really no input capacitor?
No it does, a 4.7u electrolytic. I mistakenly left it out of the schematic.
