EQD Arrows

I traced this one a while back and created the Lawn Darts PCB over on the store from it. About time I made a perf and etch layout. If a Rangemaster and an Electra ever got together and had a baby, the Arrows would be the baby. Should be an easy fit in a 1590A with the pot board mounted.


  1. Thanks for another great layout! This one looks like a nice daughter board to put as a gain boost before some amp in a box pedals. One question, I can see the electra in the schematic, but what makes this a treble booster, the coupling caps values?

    1. Yes, tho the similarity to the Rangermaster refers more to the boost control.

  2. Verified. Sound good. Tanx a lot! :-)

  3. I build one and with the level cranked the volume is only slightly above unity. Any suggestions of things to try?

  4. Thanks for this!!
    1 - What would I need to change to lower the overall gain / dirt?
    2 - If I wanted to add a volume pot - what would i need to do?
