Schaller Fuzz Sustain
An old fuzztone from West Germany which was housed in a wah shell. The treadle controlled the amount of fuzz and clean signal through a dual gang pot. There was an internal 22k trimmer which controlled the amount of gain. Built it stock which works fine but it needed some improvements like higher output level … Read more
Schaller Treble-Bass Boost
Not much info on this but, it’s a rare West German Schaller vintage “Treble-Bass Boost” from 1968. It typically goes for over $400usd, so fairly desirable. It’s a 2 transistor based booster, with a five position switch that controls the the frequencies being boosted. There’s 2 treble settings, 2 bass settings, and 1 mids setting. … Read more
Schaller Fuzz
For Fuzz Friday I give you a fun little circuit built in West Germany in the late 60s and early 70s–the Schaller Fuzz. It’s a silicon Fuzz Face variant and sounds rather good. Originals used BC109B and 239B transistors, but modern equivalents would be BC549B or 550B. It’s laid out for onboard pots, but if … Read more
Schaller Fuzz ’72
Argh. I just hate it when i draw a layout and when i’m posting it, i can’t find anything but just a few photos of the original unit – No ad texts, no original ads no nothing. Just a few images from google image search and one youtube clip from different design by the same … Read more
Schaller Tremolo
Request. I’ve already done the Hearthrob but someone asked for this, and you can never have too many tremolo options I suppose. Some of those transistors look like they may be difficult to get hold of, so I’d probably just use 2N5088’s which work fine in the Hearthrob. If you do use other transistors make … Read more
