I wanted a headphone jack at the top of the unit so I could use it in my lap without damaging the orig headphone jack or my groin- hah. I thought about having 2 additional jacks (1/4" and an 1/8") but for now just went with 1/8' for starters. Basic idea is daisy chain as many jacks as you want but only use one at a time so as not to strain or damage the circuitry. This turned out better than expected! Special thanks to my friends at madbeanpedals.com forums for helping me (because i don't know shit about electricity basically Madbean thread: http://www.madbeanpedals.com/forum/index.php?topic=10416.0
Great mod! Happy to see the voltmeter out, that wire job looks super nice. Have you tried both headphones out at the same time? I'm picturing a small jam session with someone on an ext in instrument.
Double posted by accident, but I had another question anyways. Do you think this would work on the input jack as well? An SP with more in/outs sounds very attractive.
No, I was advised that using both at the same time could load the amp and possibly damage something. It prob could be done with a small add on PCB with another amp and some components.
as for inputs, maybe same story- get some advice from people who understand this sort of thing better before attempting- I have seen people do amazing things. Check out DIY forums like I did over at madbean.
EDIT: I might look into this at a later date including the multi input idea- this could be interesting. More likely is I will just add a 1/4" jack first in serial off the new 1/8" jack so I can use whatever headphones I want from the rear panel. I will post back here either way!
