    Seeking schematic Acoustic B-1 or similar

    As you surmised that cap does not go from output to ground but rather from the +15V power supply to ground. I did find a bad 10uF 50 V electrolytic in the signal path by tracing the signal till it stopped just before the output of the board. Probably didn't need the schematic for that but nice...

    Seeking schematic Acoustic B-1 or similar

    After some searching I did locate the schematic for a model B$ which is similar and the EQ board looks identical. One difference is that the board I have has a 1uf cap across the output pin to ground, right at the coax cable. What would the function of this cap be?

    Seeking schematic Acoustic B-1 or similar

    Working on an Acoustic B-1 with low volume. I've worked on and built tube amps for audio but this is only my third guitar amp and third solid state amp. This one has a pair of 2SD424 transistors which is in a darlington pair configuration, or emitter follower? So far the power supply tests good...

    "Official" Mikro Bass Club Part 3

    Greenstreet, I already have a club number 237. This is my second Mikro, I also own a transparent red one from 2016. This new one is my backup and couch bass because I'm too lazy to fetch my bass from the basement space every time. While I haven't played that many basses these Mikros feel like...

    "Official" Mikro Bass Club Part 3

    NDB Facebook marketplace find. 2019 Mikro, purchased from an older gent, (meaning my age) who's father was going to teach him to play but passed on before it happened. It appears to be untouched. I couldn't resist the $100 price. And as a bonus it came with a stand and a beat up but serviceable...

    "Official" Mikro Bass Club Part 3

    Excellent question. My practice room is in the basement and I often like to have a bass near to hand at odd moments of the day to noodle around on. Having old and arthritic hands I find that I only enjoy plating the short scale, so desire a ground floor bass. Also being a beginner I think its...

    "Official" Mikro Bass Club Part 3

    I'm here to join the Mikro club. Still working my way through this thread but thought I'd toss in a pic of my newest and so far favorite bass. Been playing only since Aug '22 and started with a borrowed epiphone thunderbird and squire p bass then bought an Ibanez 330dx (made in Korea haven't...

    First compression pedal help

    Is there a music store where you can try some out? Total noob here but that's what I would try, just like if you were going to look at basses. Here in Portland old town music has an incredible selection of pedals. Too overwhelming for me to look at.
