Stew Mac Tape Op

[dcburn]

Has anyone any experience with this circuit?

Works as intended, but with quite a bit of tone suck. Also, the tone knob does just about nothing.

Anything I can do to alleviate some of the tone suck and make the tone knob more usable?

Can’t find a schematic, didn’t come with one.

I see your problem. The stomp button is crooked. JK. I would go thru and double check all transistor values and caps are in the right place. Its really easy to get them mixed up. Example.... a .001uf and .010 uf, or something like that being one possition off on the board or mixed up in reverse. I've built the Ghost Drive and the Two Kings, along with the Deluxe Reverb amp from Stewmac and all sound and work perfectly, but I have read of cases where people have mixed things up a little and got odd behavior. Have you called Stewmac support, they are suppose to be top notch. I would start buy checking the component locations and values first and see if you missed something. I did it on both pedals but caught it before I did the soldering. Good luck.

I didn't find any components in the wrong place and I've assembled a couple amps myself that I still and actually only use.

I think I was going to call at one point but forgot and the pedal went out of sight on a shelf.

Saw the DIY page and figured why not ask?

Really just hoping someone can point me in the direction of the crystal lattice used by Howard Dumble to make my pedal sparkle!
