This is very dependent on quite a few different things, but in general, more mids will give more punch.
Yes as stated before, more mids and a compressor will deliver more punch. Also sealed cabs and heads with fast transients all contribute to the punch.
To me, it's a sound that cuts thru, but also with certain heft at the same time, one that isn't very wide and open, but slightly compressed sound with a low mid emphasis
I would run your graphic EQ with a cut at 30 hz, minor boost on 64, boost at 125, and boost to taste at 250, and see how you like it. That's just emphasizing your low mids. Maybe a little compression on your hard notes and run the "tube" side.
Punch!! I dont know man, alot really comes from the player. you can over EQ to a point. But that just makes notes smear or bloom. whatever describing sound gets cheesy. finger style the way you apply attack to notes. can be where the punch is at. Having the amp reproduce it is easy. Just having a decent amp with decent speakers of course. But its more the playing technique than...my amp gives me punch. it does give punch...duh but it will only amplify, what the player gives it. otherwise boosting fundamentals will make certain notes "punch" more or bloom or boom whatever. I notice it alot in the 8x10 which has a alot of boom in the 80 to100hz area. So if your going up or down in a scale. Either towards the beggining or end to the note passages has a boomy ring to it. Basically 80 to 100hz is open E and open A fundamental.Some people hate it. Other use it to your advantage to approach the neck different. So any scale with a A or E can pop out a little more. Any amp with a good 60 80 or 100hz band can boost or cut this effect. Likewise you can create or cut other bands in the fundamental to fix or create the same boom. so think open D or open G you would boost or cut 146 or 195hz. So most amps would be around 150 or 200hz. you can eq the mids to pop out more by boosting 400hz and up. but all tone gets smeared in the fundamentals. so its better to boost or cut at the fundamental. and its very narrow bands. I just think EADG so 82 110 146 and 195hz. and depending on the highest note you hit G or G# final clarity is at 400hz. there is higher harmonics or course, but most of your room problems booming blooming punching whatever is at 80 100 150 200 and 400hz. fix things there first then boost or cut the higher frequency's.
Yes exactly. I run both pres because the solid state has a lot of clean boost (Im trying to get as much out of the amp as I can...) and don't forget the low filter boost on the right side. I use the low at 3 o clock and the high about 1. I also use a VT pedal and a limiter in the send/return, and those help this amp mucho. Allot depends on speakers and bass and, as stated, attack technique. This is my rehearsal space amp (I have 2, they are cheap used and reliable) and I have 1300w of ceramic speakers for it, a Kappa LF 15 and 2 Delta10s so I can crank enough to move air in a small space.
