Re: Really Smooth Overdrive! [documentation]

Thanks! Since I don't have the ability to produce a board, and would rather not mess with the other methods, I'm gonna see if I can con, errrr bribe someone to etch a board to build this. If anyone is willing and able, please speak up. I will pay, not looking for a freebie. (I would love to DIY, but...

Re: Really Smooth Overdrive! [documentation]

I know this is an old thread, but... I am intrigued. I am wondering if a gain control would be as simple as a pot and a fixed resistor in parallel with the diodes, ala a tubescreamer? I just never have liked using the guitar volume to control pedal gain. is Mictester still around? Also, did anyone t...

Re: Bogen CHB-35 info

Hey jupagblkxten any reason for Panasonics? I am working on a Bell Sounds Pacemaker Pm20, which has some 2 tubular multisectionals underneath, and I will probably need axial rather than radial leads. Have found Vishay/,BC Nichicon and Lelon brands at Mouser. If the Panasonics are better than these, ...

Re: Bell pacemaker pm-20 schematic (6v6) version

Link to the PM20 schematic. Rnfr, this is probably the same tone control you have on your amp.

Re: Bell pacemaker pm-20 schematic (6v6) version

Bought the Pacemaker as known to be not working. Bought the SAMS for it as well as some extra tubes and fuses. The the seller tested the tubes and disclosed the rectifier tube and one preamp tube as bad. The amp is basically 6Av6 (mic preamp)-->6AV6 AF amp-->Tone Control circuit-->1/2 12ax7 AF amp--...

Re: Bell pacemaker pm-20 schematic (6v6) version

From googling, probably a PM75 Pacemaker. It seems these were sort of a budget line built by Bell Sound Systems in Ohio. I think the one I bought has a similar tone control. I wonder if the preamps are the same, with different output sections? I found a hand drawn for the PM20 (not complete). The Sa...

Re: I can't keep my guitar in tune

Perhaps you have just run into the fact that a guitar is not an instrument that CAN be perfectly tuned. Give a read here about a guitar being a tempered scale. I have noticed that using a lot of fuzz or OD can accentuate the amount that this is noticeable to the ear? http://www.guyguitars.com/eng/ha...

Re: Jetter - Gain Stage (Blue)

This was the original Jetter, supposed to be Eric Johnson in a box. Recently acquired one, and as Jetter seems to not be interested in producing this anymore I degooped it. My opinion: First, I don't care too much that Jetter Red copied the Zen, would rather he would have disclosed that fact, but mo...

Re: working with waffled metal, like rectos --- plz read inside

Looks like it was done with an end mill. Those are pricey, and only work well in a CNC machine or similar. You might try a Dremel and a small cutter or stone attachment taking small bits at a time.
