    Real Spring Fet Reverb (Surfybear)

    BTW - here's a really simple spring reverb circuit (you could probably add controls for dwell etc) from an old PEAVEY amp. Uses a higher impedance tank for their teeny little tank but you can use a better nice sounding tank like a MOD 8EB2C1B Reverb Tank 800/2200 ohms. You'd want to redesign...

    Real Spring Fet Reverb (Surfybear)

    This was going to be the housing etc "concept" lol. The green glowing "spring" is just for looks. The RCA jacks go to the tank.

    Real Spring Fet Reverb (Surfybear)

    The RV3 trimpot is supposed to be adjusted so the TP1 (testpoint) is 6V. This site https://bulinskipedals.com/shop/fet-spring-driver-reverb-diy-pcb/ used to sell PCBs and has a schematic, parts list, and writeup. This is the CORRECTED schematic of mine and PCB

    Real Spring Fet Reverb (Surfybear)

    I did a PCB for this ijn KICAD and never got time to finish. I have a project file of the one I made prototypes for (with some errors) and a never one with the errors (I think fixed). If anyone wants the files etc your welcome to it. The below is my version 1 with errors - I stupidly had a...

    adding fx loop to old peavey amp?

    yeah good point I do need to take it apart and prove it. although the clean channel (which is what I mainly use) only goes thru a few and I normally run this very "clean" hence the desire for a pedal FX

    adding fx loop to old peavey amp?

    Sorry if a bit of off topic - but FX loops are a big thing with using my pedals I build. Was thinking of messing around with one of my old SS amps - good old Peavey Blazer. Was wondering if anyone would be able to give me advice on where I could add an FX loop? I looked at some of the other...

    source for DC power plugs 2.1x5.5mm ?

    thanks - saw SmallBear but their out of the short barrel ones Mouser / Digikey etc may be it. Was trying to avoid their shipping but...

    source for DC power plugs 2.1x5.5mm ?

    I want to make some custom power cable (9V) lengths. The only thing I can find are the super cheapo junk ones. Anyone have good source for the plug types like this? They shouldn't cost $3-8 for a connector. THESE NOT these

    anyone ever look at power supply voltages with a scope

    Ok - I found a great deal on a CIOKS SOL and bought one to try out. These are the measurements for volts vs load (mA). Tracks with the BOSS, nice and steady around 9.2 volts or so over at least 600mA - didnt have a load setup for 660mA. 900mA it drops to 8.5V but thats outside its range...

    low profile momentary switches NC - source?

    Thought I'd posts this pics of the TAYDA momentary closed (NO) switch insides. Pretty simple. After carefully drilling out the pins this is the guts. You could turn it into a magnetic switch pretty easy. The holes are about 0.100" (2-56 screw size) and the black plastic housing you could use...

    Modelers and analog pedals… do they really gel?

    I have a Fender Deluxe Reverb and Tweed 5E3 that I never use anymore. Just too loud with people in the house. My Boss Core GT1000 is super "touch" responsive and I can dial in what I want and experiment - using either headphones (which I kinda hate) or FR monitors at super low volume. But its...

    anyone ever look at power supply voltages with a scope

    As another piece of info - why doesn't anyone post Volts vs mA load for supplies? This is a collection I've taken on misc supplies. Kinda interesting. The other piece of info of course would be the voltage vs time showing any spikes. For instance the digitech looks ok for regulation but has...

    anyone ever look at power supply voltages with a scope

    Nice -looks like a cool setup. I've gone pretty much all guitar but I still have an SY77 sitting 2feet from me. Needs a backlight update.

    anyone ever look at power supply voltages with a scope

    I'm guessing the Eurorack stuff is pretty picky - probably not high current? I've done linear supplier forever but a) they're big b) have to be sized carefully for the application or you waste a ton of power into heat, etc. Sort of why I've been experimenting with SMPS. A lot of garbage out...

    anyone ever look at power supply voltages with a scope

    how do you like your DC7? Expensive -but worth it? ... I have a lot of 200 series Boss pedals a GT1000core and hate all the separate power power supplies.
