First question: I have a RG7620 I am wanting to completely upgrade to the highest extent I can. I already ordered a Tremol-No small clamp, but after doing so, I remembered I wanted to upgrade to a brass big block for my LoPro. Will the Small clamp tremol no fit on the brass big bock? Or did I just screw myself over? Lol Will the big block improve my RG7620's sustain and tone? Or will it make it sound muddy due to the guitar using basswood? I heard somewhere that the brass blocks don't do good in darker woods, and from what I hear, basswood is a dark wood? Any advice on that would be greatly appreciated. This is the brass big block I am going to purchase: Ibanez edge 7 string big brass block bridge upgrade - eBay (item 290370094884 end time Dec-14-09 05:27:48 PST) Second question: Are the noiseless trem springs worth $10 off Floydupgrades.com? Or will I get the same effect from stuffing the springs I have now with foam? The ones I have now are brass by the way, I don't know what the other ones are made of. But heres a link to them on Floyd Upgrades: Noiseless Springs [ANS0001] - $9.95 : FloydUpgrades.com!, Floyd Rose Tremolo Upgrades Third question: What are the best volume/tone pot to use on this guitar? Do I order mini pots, or standard pots? I have no idea what type of pot to buy, I was overwhelmed at the large selection to choose from. I was leaning toward 500k Mini pots, but is there a name brand out there that work, and sound better? Fourth question: What is a really good 5 way pickup selector? I am thinking about buying a Schaller Megaswitch, if there is a better one out that would have a better connection, and a clearer tone, please steer me in that direction. Fifth question: I know it may sound dumb, but are the BKP Painkillers, or similar worth the extra $100 over the Crunchlab, and Liquifire combo? I have never played either pickup, but if the BKP's tone justifies the extra $100, I would prefer to make the jump to those, rather than the Dimarzio set. And if I got the BKP's, will the pickup tabs fit in the Dimarzio tab holes with no routing needed? Thanks ahead of time for any advice, and opinions. I've never ventured off past pickups when it came to the electronics of a guitar until now. I've always stuck to simple soldering, and setups, so every bit of advice is valued.
