I wasn't sure whether to put this in Effects or Amps and Cabs..my apologies if this is the wrong sub forum. I am looking at options for headphone practice and can't seem to make up my mind. Background: I already have a decent set of cans (ATH-M40x) but don't have a small footprint way to practice through them. I do have an older combo amp with a headphone output but no aux or bluetooth input. Ideally, I would find something with a smallish footprint that had a headphone amp with enough juice, an aux input and/or bluetooth (independent aux volume ideally). I also play 6 string guitar so something that did double duty bass and guitar would be a plus but not required as I have other ways to deal with guitar practice if need be. My sonic preferences: I often use the 'just right' size tube amp for bass (and always do for guitar) so that I can live on the edge of breakup. If I dig in I can OD or if I roll back the volume I can clean up a bit into warm Stax-Volt-Motown land. I have recently come to appreciate the sound of the GK RB series. The GK's and an old Traynor Monoblock are the only non tube rigs that I have truly vibed with, but in all fairness I have no experience with modern higher end class D rigs such as Mesa, Aguilar etc. Solutions I have considered: 1. Phil Jones Bighead - I worry that this will be a one trick pony and that I won't like the trick. In my limited experience with Phil Jones (4B cab and Briefcase Combo) the tone was very modern (for lack of a better word). Both products were good quality (and surprisingly loud and clear) but not really to my taste. 2. Ampeg SCR-DI - I like me some Ampeg tube amps and the Ampeg tone in general but the only modern Ampeg product that I have mucked about with is the Scrambler OD pedal. There was nothing wrong with the pedal but it was an overdrive that I didn't really care for and took back to the store immediately. As affordable as the SCR-DI is, I am not sure I want to pay for and carry something that I know I will only use a portion of...I can't image ever engaging the OD function. 3. Line 6 HX Stomp - This probably makes the most sense (the most control, will do double duty guitar and bass)...but at almost twice the price of the second most expensive option here (Plex). I also worry that I will spend some time mucking about with menus vs. practicing. I also worry that like all modelling products that it will depreciate very quickly until it is eventually worthless (I bought an AXE-SYS 212 when it was first released). 4. Palmer Pepampbass Portable Bass Preamp - I have never heard of this maker or heard any demos but it seems to hit all the check boxes, has a nice form factor and decent price. I wish I knew more about it, the maker and its tone. 5. GK Plex Preamp - Kinda expensive for what it is but if it can make my cans sound anything like the 400RB through an EV loaded 2x15 it might be worth it. If it could make a crappy backline rig sound like that as well then even better. I'm sure there are solutions that I am unaware of and I am happy to hear them. I would be especially interested in suggestions of common used gear that is similar to the above. I do not have a set budget but do not need to hear about products that cost more than the HX Stomp (799 Canadian). Thanks in advance for your help.
