mauman's got a solid strategy, I'd definitely start there. Experimentation is fun 

: I've seen some chain order diagrams have: guitar -> tuner, EQ,  dynamics, wah, tone (od, fuzz, dist), then modulation, then delay, reverb, etc -> amp.

But then some put the eq after od/dist... so yeah, experiment.

Some fuzz circuits (mostly two and three transistor fuzzes) don't like having anything but first dibs on the guitar, so manage impedance accordingly.

But what do you do if you suddenly want a little more out of it? Bend over and adjust the gain control in the middle of a song?
Yep.

Could do a second switched setting like one does with a muff? Not advocating one over the other  just thinking out loud.




But the dumbell seems neat to be able to do that so simply, kind of like a pseudo second channel with the boost switch.

I haven't messed with "amp" pedals much, but maybe because I've never asked anyone about them; why they exist, because my ignorant take is "wtf do you need an amp person if you already have a good amp? Does it make a bad amp good?" Which is very reductive on my part, but it's what's in my head and why I haven't ever asked. Same reason I've never done preamp perhaps a good thinking about. But they do exist and people use them, so there's something to them.

But your line, " it doesn't sound like a distortion pedal on top of an amp. It sounds like an amp." sums up the appeal.

How does this compare to something like a BJFe Honey Bee? Different circuits obviously, but as far as sound and function. 

Might have to build me a trash compactor now 

I wouldn't have traded it for anything.

I'm feeling that. These hooligans are growing up too fast. Always happy to help them in the music department, but harder to get up and move. You can tell which is my favorite 

I'm not seeing any of the images

Scholar. Gentleman. King among men. Thank you!

My youngest caught a baseball tonight. Little things, y'know. I'm glad they're trying new things and glad they can convince their old man to go out ...and earn that daily ibuprofen.

Not prompted by the latest releases in the pedal world...

Anyone have the schematics for the old Boss KM-60 mixer? Through searching I've found a lot of AI slop and spam sites, but no actual schematics for this one.

Even something like the Ibanez RM-60 might do for what I'm thinking of. I have no idea if other contemporaneous mixers to it would be similar, but won't know unless I have look at them.

Thanks.

Another thought was you might try piggybacking two NPNs to get a lower value. It'll make an already thick circuit a bit thicker, but worth trying.

I really like the D9E and D9D in this one. I also tried silicon here but it was really harsh, but breadboard it; you might like it    Here are a few other NPNs that have that are pretty low, <100 hFE mostly. I measured these with a T7 component measurement tool:

part num	type	min	max
MPS3394	NPN	60	90
MPS4274	NPN	70	90
MPS5131	NPN	20	100
MPS6512	NPN	30	90

Swap in "2N" for "MPS" and they may show up that way, too.

Which one end up your favourite out of curiosity?

Probably HAIRY or CRUNCH CITY PART II --- you can use any low-gain NPN in Q6, the A5T ones are unobtanium, but there might be some MPS6512s around. PM me if you want a set. Maybe I can send them in a flat mailer on the cheap 

Sorry to have taken over your build report... Here's my drawing:

Hah, yeah after a number of good folks here suggested it, I went back to mid to mid-low gain transistors. I mean, 5088s will work, but going to lower gain reduced some of the unpleasant tones.

I read that write-up of Aion's as well after my first (terrible  ) version of it, which helped incredibly.

I went and made silly names for the combination of NPNs that I tried, even. 



I'm not sure if the Qx part numbers line to Brian's , but I'll post it later tonight or tomorrow.

Okay, here's a comparison. Forgive the top (original) drawing, because it's terrible (my first redraw of a schematic) and the part numbers differ . Compare to the bottom (modified). These are mods I pulled from the interwebz, not my own original ideas. NOTCH was renamed FILTER in the new schematic. R21 and R22 are removed, C14's value is changed, pin 3 has been reconnected at the net between R23 and R24. and pin 1 is grounded.

You'll also notice the clipping trimmer. I find 1k is sufficient, but maybe for larger amps it makes a difference to go up to 10k.

WBB!
