There is no such thing as 'plastic soilder'. They are soldered to the board like every other pedal and then i would assume reinforced with glue.
Although looking at online screenshots, they are not glued. Its probably a bit of flux paste left on the board. Behringer screw the boards in place...
Although he might have an amp with two separate inputs. So an ABY would be able to switch one guitar line to between the two amp inputs
Passive would be fine for this usage, any thing else would be overkilllllllllll
Had a few
Kalamazoo - nice pedal, quite thick so i tended to use it on the bridge pickup where it excelled
200lb fuzz - fat silicon fuzz
JTM - basically RHCP in a box - one knob, very simple
Butterfly Chorus - quite rare, tweakable CE2 style
Les Luis - this was a clone i built. Very simple...
Yeah i know the difference. Whammy pedals allow you to mix the original note with a pitch shifted one so it can harmonise to a degree. Sure it won't do the scale matching, or let you mix two different notes with the original but it allows you play two different notes at once.
The ricochet only...
