I desoldered it using a solder sucker. It takes a little skill. You could easily just cut all the pins off if you are intending to bypass it.

Hi,

I have told a friend that I would look at his (non-working) piano.
It has the same LA4558 and it seems fried.

I have some TDA2030 (stereo amps) and I would like to bypass the amplifier like you did.

Did you cut out some pins of the LA4558 to remove it (electrically) from the printed circuit?

Thanks.

I had a poke around mine today and had a bit of trouble finding bends…. you need really thin probes that I didn’t have.
I did find however that you can find a tempo pulse firing up the tempo LED and rig it up to a few other select switches on the board and it will sequence or step through the pattern and melody select matrix.
Pretty cool. Whole thing sounds nice distorted too.

Nope, I’ve never put batteries in mine. Check the voltage and polarity of your power input.

Nah, I haven’t done anything with this one. However I have bent wavetable synths before, the best thing to do with them is identify the data and address lines to the ROM and connect them to each other either through switches or pots.

hi, did you bend the ms710 already? i want to bend mine too (very soon)so maybe we can exchange some bending spots
