Yep, that was sort of my original plan. I was going to use a bass boost potentiometer, but after trying four (an Alps 10k, a Vishay 50K, a Panasonic 50K, and some Australian 100K pot), I gave up because I hated the sound. Matched resistors and a switch sound much better, although the boost amplitude is fixed. I only mounted the switch on the side for this first build because the switches I have sitting around are too large.

My final design utilizes an ultra-mini toggle switch mounted in between threaded 3.5mm jacks (no more hot glue):

Yep, sounds great. "Circuit board" is there just to hold things in place, no traces, all connections are done with old Siemens & Grundig wire.

I am not meaning this in a negative way

But that is the strangest looking stand I have ever seen in both material and looks :P

I sat there just wondering what that thing is made of... It looks cool how it shifts from one color to the other and it just looks so different

Mind telling us what it is made of?
