Re: Gilmour Fuzziness...
Well, there can be problems or issues with lots of things and it's player/rig dependent...something that is an "issue" for you an your rig might not be an issue at all for me and my rig so a lot of times when a builder "fixes' something it's because he has a problem with a piece of gear in his rig.
In addition to that it has been my experience that when tweaking things in effects (or guitars and amps to be honest) you have to be very careful because you can often loose something that shouldn't be lost.
A lot of this old gear has warts, issues and parts of the whole package that buy us as players and sometimes they can be corrected, fixed or in some way made better but then you've lost something important...remember, changing things no matter how small will have an impact on the overall results in some way.
There are lots of good clones out there!
Keep this in mind...a good late 60's Si Fuzz Face is over a grand now, mid 60's Ge Fuzz Face almost 2 grand, some old Tone Benders are breaking 2 grand, original Rangemasters are bringing 3-4 thousand, a good Clyde Mc Coy wah is over a thousand dollars now...even funky MIJ pedals form the 70's are bringing $400, $600 even more so clones can be a GREAT way out for many players today!
In the fuzz world AnalogMan does great Fuzz Faces with his Sunface, the newest Dunlop Fuzz Faces are tops, Hartman makes a good Fuzz Face, BMF effects does a great Fuzz Face as well as Tone Bender and a killer Big Muff plus a new wah that's about to come out, Kevin Wilson makes some good wah pedals as well as a few other things...the list can go on and on and on and there are dozens of other big and smaller builders I didn't mention because we'd be here all day!
It's really simple...do as much research online as you can with reviews and sound clips and if you like what you hear take a chance...if you like when you get it home then enjoy it!
