MOSFETZER boost

[Xavier]

 

OK don't panic.

What I've done is tearing apart my Peppermill and putting in a fetzer valve and a mosfet boost IN SERIES, hard wired. The mosfet boost at minimum pot position is unity gain / buffer, so I wondered what would happen if I did.

Interesting result. Still testing but the warmth of the fetzer combined with the crystal clarity of the mosfet boost is a curious combination....

Hi xavier

you got a PM

I had plans to do some thing similar with that bassman fetzer I had done, it needed more boost to it, but then haven't found a lot of time to. Would it be possible to get some sound clips?

Let me know if I got this right - a fetzer on as a 1st stage and mosfet boost as the 2nd stage - right? Or, is that the other way around?

I took my Vibin' Champ and put Peppermill front-end on it, I really like that combo too - there's a lot of tone/charactor that comes out with a good clean boost.

Sounds like a cool idea - my 2 stages-of-boost experiments have always been good ones.

Yep. Fetzer first and Mosfet booster after . I thought that was the most logical order.

Interesting and highly interactive combination. I think I'll have to roll off some of the bass content in the fetzer, otherwise the bass gets boomy and farty when you push the mosfet part.

How do I roll off some bass in the fetzer part? different input cap? smaller?

Nothing really new under the sun. It becomes a two stage OD / boost with independent gain stages for each. I think it's worth working on it a little more. I guess I want the mosfet to be full and clean for the most part, and the fetzer part to add some grit.

I still have to test it with my band and see how it behaves with the rest of my pedals.

Change the coupling cap between the fetzer and mosfet, make it smaller to filter out the lows. Or, try implementing the tone controls from the Fender amps between the stages (just like Fender amps do, btw) so you can roll off whatever amount of  lows and highs you want. That's basically what I planned to do.

this sounds exciting, might have to work it up. i'm going to be doing a lot of dual effect experimenting in the new year, so this will be a good place to start.

Interesting... I just finished a similar project. http://i112.photobucket.com/albums/n188/ubersam/FahrgingBoostard/DSC00155.jpg I took the AMZ mini-booster and the Sparkle Boost, housed both in one box and made them selectable via rotary switch. In the middle position of the switch, the AMZ is fed into the SB. In that position, the pedal becomes more of a distortion than a booster.

Well the minibooster to me is not such booster. It is a distortion pedal !! at least the one I built had LOTS of gain
