I desoldered the LTC1044, which was a little tricky because one of the pins is very close to a corner of the ribbon connector, and installed a socket. I ordered several LTC1044s from Ebay, so have extras in case the IC fails again. The fix worked, and the guitar is functioning, so that is good news.

Are there any copyright issues with copying the board? It looks like there are a couple of incomplete efforts to create a parts list. I have several questions about the current circuit diagram, as it is incomplete and uses some non-standard symbols. Specifically, the transistors and a couple of the ...

Since there appear to be no source for replacement Fishman main boards, has anyone checked into whether the original board Gerber file is available? Doing small runs of circuit boards is surprisingly inexpensive. I would suggest selecting a more robust ribbon connector, with positive mechanical lock...

Here is photo of circuit to Q1 and Resistors R1(10K: 103) & R3 (20K: 203) . The Base pin is on top, and the Collector and Emitter pins opposite.

I have been trying to figure out how the Fishman Fly Rev 1 board works. One issue I have run into is that the pinouts of the transistors on the board are not consistent with the datasheets. In most of the datasheets, the Base and Emitter pins are on one side and the Collector on the other side. The ...

Peaches, could you confirm that all the transistors are either NPN or PNP BJTs? I have a Fly1, Rev 1 Fishman board and the SMD markings are slightly different than those listed in the schematic. Has anyone tracked down compatible SMD transistor replacement part numbers? From SMD markings, there are ...

Hello, I'm an electrical engineer new to electric guitars and am trying to help a friend with a broken Fly Classic main board. On preliminary inspection, it looks like the LTC1044 Capacitive power inverter is not working to provide Vee (-9VDC.) Before I really dig into it, I have a few questions: 1)...
