Nice job on this! Thank you. Went together in minutes. Surf’s up!

The smd soldering turned out to be easier than I thought, this is perfect for amps that lack reverb.

The pedal is not well thought out IMHO. The tremolo effects are also behind the mix knob, which makes no sense to me. That’s what the switch and the intensity control are for. So you can only hear the tremolo effect with the reverb nearly fully wet in the mix – and that’s awful. This makes the idea of the tremolo in this pedal completely useless.

I love this reverb and with a little creativity, you can make it even better. This is IMO, the best Spring reverb emulation you can get and with the dry mix built in, the controls are very powerful.
As for the Tremolo feature on the second two switch positions – the complaint by a previous poster can be eliminated by either doing what I did, which is replace the resistors controlling the tremolo signal with trimpots using the handy Trimmit boards or socketing them and changing them out until you like them. This is an excellent Reverb!

I personally haven’t played the hundreds of dollar reverb pedal (your Strymons and the like), but this has got to be close too them. This has drip. This has space. This has everything it advertises! Great pedal and simple enough build (I got the F-1 chip pre-soldered).
