Okay, here's a bizarre one. I bought a minty clean Fulltone Supa-Trem ST-1 off the local Facebook marketplace, I mean minty, box, factory manual, even the little Fulltone sticker. I get it back to my shop, works beautifully that night, gorgeous vintage Fender BF tremolo tones with more versatility. Played it all night.
Next day, I go to show it to a client and it's not tremoloing. It's lighting up, signal is passing like it's bypassed, clean, no clips or bad distortion or hih/low vol spikes. Power light clicks on off, hard/soft LED clicks on off, speed is controlling the flicker of that LED, everything working great, just no bup-bup-bup-bup.
I go to use it that night, it works fine. Go to use it the next day, working fine. Later in the day, not working fine.
I finally figured out that it seems the catalyst of what's apparently intermittent tendencies is the temperature of the room. I keep my repair shop hovering in the high 60s most of the time. But I turn off the air when I'm soldering (my station is by the blower) or if I'm simply cold. It seems if the room goes above 70 degrees, the trem function no longer works.
What you guys think? Bad solder joint that's ever so slightly expanding or shrinking just enough to crap something out? An iffy chip? or what are they in nice old skool trems ... photo sensors?
I haven't reached out to Fulltone yet, you can't call or direct e- them anymore unless you provide video of your problem. Until I make a video showing my thermostat haha, what y'all think?
