Rothwell Love Squeeze

Here's a nice little compressor that should be a fairly easy build. It doesn't have the squish of a DynaComp, but goes for a more subtle compression like the Orange Squeezer. Board mounted pots and an easy fit in a 1590B. Here's the schematic for reference.

  1. OMG I was just watching how it is compared to 4knob keeley. This wins it!! AWESOME!
    surely build it

  2. are you sure that 10uF below the volume oriented correctly? just wondering

    1. That's how it is in the schematic and a verified stripboard layout I referenced. So yes.

  3. Very good, I was waiting for a layout of this pedal ... Thanks

  4. AHA, finally. A good perf Lovesqueeze layout
    Can 5819 replace 5817?
    and is good replace 10u with MLCC?

    1. Don't know for sure, but probably.

    2. I'm thinking the same, 5819 for 5817. how's the result?

  5. hi,

    I cant seem to find the transfer image...

  6. Not build yet... but double check with schematic everyday, looks like everything is fine, but dont know the effect about replace scothky diode,.. must to try it

  7. Interesting conversation about the diodes of this compressor:

    Both BAR43S and BAT43 have the same forward voltage (already checked), so you can use the latter. I would use sockets and try BAT43 and 5817

  8. You can mark this one as verified. I just finished the build - it sounds great!

  9. I build this using 2n5458 to replace 2n5457, and a pair 1n5817 to replace 5819. It works, but when I turn up the comp pot, the sound gets louder and bassier. any clue?

  10. Built one, but it sounds weird. The compression is not really subtle in my build, the signal is being 'pumped' way too hard (especially when playing soft on lower strings) on every position of comp pot. Used 5817 diodes and 2n5457 transistor.

  11. Ciao, ho Sentito il video e suona benissimo, COMPLIMENTI!! VOLEVO CHIEDERTI SE c'è il disegno elettrico. Devo farlo subito perché è bellissimo!!

  12. Q bc5457,,,,OR BS170,,,or,,bc549 is good? Provisional. Grazie, sei bravissimo. Saluti dall'Italia.

    1. It needs to be a JFET like a 5457. The BS170 is a MOSFET, and the BC549 is a BJT.

  13. Hello!

    I made 2 of these. I didnt have any 2n5457 when i made the first one, so i used a 2sk30 with twisted pins. Other than that, they are identical. And the one with the 2sk30 sounds a lot better. The 2n5457 one distorts easily, and has a trebly kinda noise to it. What purpose does the transistor serve in the circuit? Could it have this big impact, or have i done something wrong on the 2n5457 one?
