Skybone

Anything by The Cure?

Bullet the Blue Sky - U2

Yamaha BB's.

Bad Reputation - Thin Lizzy

Matsumoku is definitely the way to go, an Aria Pro II or a Westone (Thunder II or III). Ibanez are always a great choice, maybe a Musician or Roadstar.

Over and Over - Black Sabbath

Remember licking 9v batteries to see if they still had charge left? Wonder if that'll help? Very interesting article though. Wonder if they're going to do any further studies into it?

Sands of Time - Fleetwood Mac

Ventilator Blues - The Rolling Stones Oxygene - Jean Michel Jarre

My Iron Lung - Radiohead

Just Breathe - Pearl Jam Breathe - The Prodigy Gasping for Air - Autopsy

Malice Through the Looking Glass - Cradle of Filth

Just a suggestion, as I got the impression you were saying that they weren't punchy enough.

@Maude, have you had a look at the Gemini Pickups Waveriders? Plenty of oomph in them. I put a set into my Walnut, and it sounds very punchy indeed.

Walk Like an Egyptian - The Bangles

His Daughter Caroline - Chuck Berry

Caroline - Status Quo

Sweet Caroline - Neil Diamond

Stingin' Belle - Biffy Clyro

Very nice looking amp

(Still A) Weirdo - KT Tunstall

The Seeker - The Who

Blame it on the Boogie - Michael Jackson

It really sounds like he needs to get his guitar checked over by someone who knows what they're doing.
