So, remember the SPAMP+? It was a ton of fun. I wrote to ask the SpampMAN if I could get a ¼” stere-to-mono adapter for the headphone jack to make the headphone jack essentially an “out” for a guitar amp so I could use the Spamp+ as an effect or pre-amp.
Dude is solid, and sent me one! He may include it as an option with future builds! The grilled, chilled, & fried all work as you would expect and sound gorgeous coming through my Blues Jr.

Here I used my New York Pro StarGazer (with GFS Lil’ Killer Rails) into the SPAMP, then my Fender Blues Jr. The tones are still awesome! the volume differences are there, but if you pick one & go that rally shouldn’t be a problem. This is totally cool as a pre-amp effect! There’s no on-off, but I do have an A/B/Y switch that I could maybe use to put it in & out of the loop. At any rate, this is still super fun, and that’s what it’s all about!
I would say this cable is a resounding success!
