Swapped the NJM4558 IC-s in every monitor with OPA1602 IC-s and also removed the limiter circuit.
Now, they don't push exaggerated mids that much, and are a little flatter. A little better for accurate mixing and monitoring.
This remains now a hobby, but I used to do: Handmade clones of Guitar & Bass Effect Pedals / Effect modding / Rewiring and Guitar Setups+levelling+refrets / Amplifier Repairs / General Audio Repairs

Yesterday I've finished the second attenuator clone of my first clone 🤣 (SPL Reducer).
Absolutely useful, even if only resistive, and didn't have to pay 800+ euro for the originals new 🫠😱
Now I can have my stereo setup with an attenuator per amp/w. two cabs each.
Specs:
This clone is based on the TC Electronic Integrated Preamp, but this also has a buffer at the circuit input, always connected when switched on. Bypass is true bypass.
This is basically what the Fortin 33 is also (a previous clone of mine as well), but I missed the control for bass and treble and I decided to do this version as well.
For some reason I got bored 😆 and used mostly carbon comp resistors and partially some different type caps.
“Mojo” …. if you will haha.
My “Fortin Zuul” clone (157th pedal built), with some modifications and an added switchable buffer on the Key in/through.
This pedal is actually the noise suppressor/gate from the Marshall JCM800 Kerry King head in a pedal.
Was tinkering with my project Jackson DK 1997 Japan guitar.
Installed a new Gotoh Japan trem, took care of the fretwire a bit, just needed some extra side recrown sanding work and follow up buffing.
The actual body had some ugly superglue spots combined with other things but I managed to buff the nasty stuff out.
Used some older real deal 90s non connector version EMGs, and for fun I actually used ~24V ⚡️ 😈, not 9 or 18v (one can do this with 2x type 23A <12V batteries>, by using a smaller dedicated holder). Remember that EMGs can take up to 27V on the internal preamp.
Sounds great and cleans up nice also, since the headroom is better. The response seems better as well.
Had to use extra shielding paint on the upper rim of the cavity and I also made screw inserts so that the lid is easily accessible with no wood screws anymore yay!
