I'm trying to find a solution. I'm somewhat of a newbie but not really. Over the years I've played in some terrible spaces acoustically. And guitar/ drums that are way to loud. I wish there was a product (maybe there is) that was like the headphone amp below but with a DI direct out to go to my amp. I'd like to hear more clearly what I'm playing. I know this can be done using some gear, but did know if my idea existed? Basically wish my bass had a headphone jack on it lol. This below but with 1/4 output as well? Hope that makes sense...
That PM351 looks like a pretty slick unit. When I use IEMs at a gig, I'll put my bass into one channel and the monitor feed in the other and pan as required which essentially functions like the PM351 does. Don't know if you're needing it for gigs or just rehearsals, but a small mixer would get the job done as well (but would serve as an anchor).
