Looking for advice on a new rig. Posting all relevant details. The band I am jamming with now out scales my current equipment. The previous bands I have been in have been lower volume than the metal band I am currently jamming with. We play in D standard, with some songs in Drop C. I am using an ESP LTD B-254 with a pick and limited finger style right now. I do have allot of freedom in the low end as the guitar players run more of a mid range sound, so I do not have to compete with them hogging all the lower range. I will be competing with a Mesa single rectifier half stack and a Peavey 5150 half stack. In practice the guitar amps never go above 5 master volume, and they have an Acoustic 370 head that I have been using, so far the volume on it has not been higher than 5 also. Not sure how long I will have access to the Acoustic head. So my dilemma is that the only thing I can reuse out of my current rig is a 4 ohm 350w 15 inch cab, And I am stuck between the choices of get something to get by and risk throwing money into a slightly adequate rig because of short notice budget or holding off and waiting until I have more cash to throw at the problem. What power range should I be looking at to be realistic? If you are playing in a similar situation what equipment are you using? Thanks for the help.
