Does Anyone Else NOT use the Clean Master?

Post by tictac »

I always keep mine full on, I'm thinking about hardwiring the clean preamp out and using the pot as a tone control for the OD channel.

I don't like the long leads to the Clean Master pot either. I get oscillation if I don't keep the lead dress just right, maybe It'll improve the tone too.

The amps that I build use separate master for Clean and Overdrive. Normally I set the Gain (first volume) to somewhere between 1:00 and 3:00 depending on the guitar. I then use the masters to control the overall volume.

I feel you have to run the input to the OD stages pretty hot to get the right overdrive sound.

YMMV,

I'm right with Gary on this one. In fact I want to change my clean master to a linear pot because typically it's adjusted at almost max, right were the audio taper is most sensitive. By putting in a linear I think it'll be more controlable. :?

For a Boogiesque type of distortion I agree you need to crank up the clean preamp which is fine if your only playing distorted. But if you want to switch between clean and distorted it doesn't work too well. (at least on my amp)

I like to set my amp up for a good clean tone which means some midrange dip, then for the OD tone I've got the OD level cranked all the way up and use the OD master to set the OD volume. If I want a thicker OD tone as you guys are talking about I've got the mid-boost circuit installed in the clean preamp section with a 1 meg trim pot to set how much boost I want the OD section to see.

This way I can retain a nice clean tone but still hit the OD channel hard if need be.

My mid boost is wired so that the clean tone stack is bypassed when the boost is engaged so it's more of a boost than just having a larger value treble cap as in most of the drawings I've seen.

This is exactly why my last build is 3 channels. The first is very Fender like in the tone stack so the mid scoop is there. I want one additional mod on the bright switch, I'd like to have 2 levels of bright. Right now I have a 120pf and it's pretty dramatic. I'm thinking a 47pf and a 120pf on a 3 way switch.

This makes a very versitle amp. I posted the schematic on the files page.

Tic tac,

I found I never really use the clean volume much ... I always liked it at halfway. Since my chassis is a 70s design (Bangkok chassis) and the circuit is the Hybrid-A, I only have the master volume on the front panel and the clean volume on a trimmer pot wired internally. I set my clean volume to match with the OD level ... :(

Mike.

Sounds like a good idea but needs lots of real-estate to implement too. I've got an inboard Dumbleator which has taken up any extra room inside my chassis I may have. Actually I had to build a "2-Story" PI board. PI input on the bottom and the PI output on the top, so I'd have room for the Dumbleator circuit on the main board.

My amp is a 100W 70's ODS circuit but with a modified Skyliner TC, midboost, and internal Dumbleator added. Also my chassis has the tubes on top.

I'm liking the tone, both clean and OD better since I added the Skyliner TC, the lower mids seem to be more promenent now.

The 3way bright switch is a good idea. I've got one and really like the versitility it adds. The way I have it wired is: 47pf across Volume pot in and center-wiper, 70pf and 200pf on the 3way switch. Up postion is 250pf (200pf plus the 47pf) middle is 47pf and bottom is 120pf (70 plus the 47pf)
So it's like a Deluxe Reverb (47pf) Standard BF Fender (120pf) or beyond. The 250pf setting actually comes in handy with the OD channel...

Well because mine has the slide switches, I screwed a 3-lug terminal onto the screw post from one of the slide switches and soldered my clean volume there so I saved from using the real estate on the turret boards. :lol:

Question: Some of the schematics show a Clean Master and some show an overall Master. Is the overall MV wrong?
