Have you tried it on a different amp? Because really a Tiny Terror + 2x12 cab with GH30 is not the best combination for such a low tuning. You're "toying" with the thought of altering caps, which IMO will do absolutely NOTHING to improve the tone, where 50-80 extra watts would help the power amp stay much more stable with such low tunings. Add in a pair of Electro Voice EVM speakers and that would make a world of difference, as opposed to changing pots and caps.
What you are saying makes a lot of sense, donŽt get me wrong, but for me and my situation I still have to respectfully disagree I am afraid:
My setup works very well for what I do most of the time. This axe really is an exeption. It even works very well with a seven string axe which basecally is only half a step higher.
Therefore I still fail to see how the amp and cab are faulty.
I had this adjustment period for every new axe I got (even for the one with RY and Mule combo in drop D, which should work well with this setup), getting used to the sound, the behaviour and eq of the new PUs. And a lot of hight fiddeling.
Also, 90% of the time (I could use it once a week if I am very lucky) a higher wattage amp would simply be too loud more my needs if I did not also put in a power brake I am afraid, plus there is always the money issue.
You must also understand that I am not going for a typical high gain metal sound, but rather a Petrucci esque version of crunch, which this amp and cab do very well for my taste.
I wanted to change the caps for better ones while I was redoing the wiring and chaning the pots as well. I am not thinking they will change my tone very much at all, I just want the extra split options, which I am sure will sound different. If I could do that with my current pots I would, but they are not push pull.
I was asking for recommendations to not get shitety ones that would possibly make my sound worse.
Also I was only thinking about changing the value on the neck as there is a bit of hight content I donŽt really like that is also fixed by rolling the volume down to 8. Just thought I could maybe do that with caps too.
I thank you for your advice, but maybe you can understand why I have trouble to follow it. ;)
