I have this nice sale going on for 60euros one guy is selling a MIK Squier Champ 15GR and he states, that
this model has a spring tank etc etc..
Its on facebook marketplace
Ive been collecting money for the surfy bear pedals, but I thought, If this one has an springtank could it be modified into an
pseudo pedal to use in front of my little Fender Pro Junior amp (or thats a dumb idea)
Or thats too much of big effort and soldering and what not.

Re: Question about an Amp/Spring Tank
I have built a reverb unit in the past, even etched my own PCB.
From the label on the tank it looks like it's a 600 ohm drive coil, 8.2k pickup, pretty standard for Fender designs. The circuitry to drive it is probably the same as the Fender amps of that kind; see http://po-ru.com/2023/03/24/upgrading- ... -amplifier, not hugely complicated. If you're using it as a pedal you may need additional gain to the drive stage (as it's expecting to be driven at around line level) , which you could do by adding a couple of resistors to the op-amp's inverting input like the pickup amp stage. If you're using it as a pedal you'll probably want a dry/wet blend stage as well. Also, if you're planning to use it as a pedal allow for a suitable power supply - that circuit shows +/- 15V. There are workarounds to make it usable from a single rail PSU but that's left as an exercise for the student
