can you drop that triode in to replace a tranny? (with re-biasing, of course!)

I don't understand the question.......

sorry about that, didn't word it too well... i blame caffeine + lack of sleep!

Would a 7806 triode be a suitable replacement for a transistor? Or do they have a different function altogether?

Rick,

Where'd that superheated section come from?  I'm kinda curious what that does/how it works.

*Doh*  I knew it looked familiar.  I actually even looked at the app note in the AN-32 datasheet that the mini-booster was based off of while trying to figure it out.

I am planning on building this pedal (the second version posted with superheated/hot setting) but was wondering if you could help me with a few questions.  The 7806 is going to be hard for me to come by, so would a 5.1V zener and .7V silicon diode in series to ground work; or should I just use an adjustable voltage regulator?

Also, would a 7V zener and 3x .7V silicon diodes work for the 9.1V zener?  

I don't have the 2n5457; would any of these transistors work in its place?

J201s and 2N5457s are easily interchangeable...

You could use a 7805 with a 1n4148 between pin 2 and ground instead of the 7806. That would get you 6.2 volts.

Instead of the zener you could use red LED (as in the ROG Peppermill) or even a 1n418 (I believe?).

So how's it sound??

Just as I remember it. It's been a while since I breadboarded it. I'll get some clips up later this week.

I drilled four 5mm holes, used a 4mm round file to open them into a slot, then used a flat file to finish it.

Jesus. That cut looks so clean you'd think it was done by a CNC.

Hi,
I breadboarded this thing and found it was too gainy (too much fuzz like!) wit 1M grid leak resistor so I went down with the resistor until I found the best value to my taste: 100k.

This demos are made to show extreme settings of this pedal.

Both demos:
- Pentode Mode
- Godin Exit 22 Guitar -> Breadboard -> Yamaha F20 Amp -> SM57 -> Presonus Audiobox Interface->PC.

Demo 1: Hot Mode - Gain at Min - Moving Tone control from Min to Max

Demo 2: Superheated Mode - Gain at Max - Moving Tone Control from Min to Max

excelent....

i liked the "low gain" mode more than the other, as with "max gain" it sounded to fuzzy...


nice demo!

why can't the god of tubes give me 2 tubes my mail?  :icon_mrgreen:  :icon_mrgreen:  :icon_mrgreen:  :icon_mrgreen:

Just finished this genius pedal.

I'm loving its versatility as it can go from a TOTALLY CLEAN tube sound to a harshy fuzz with a lot of gain and passing through great overdrive sounds!

I noted it was thought as an amp because it has a dual gain mode preamp, a dual pole tone control and an output tube that's being driven for those two things... Beautiful sound.

If anybody was asking about clean tube sound boost IT IS THE ONE. I was very happy with my modified THOR for its clean compressed sound until I tried this (not that Thor is a bad pedal, tough)

Thanks for your work, Rick, impressive pedal for such few components.

Pics!
