I'll take TM over Mesa boogie hollywood.
But it's LA there is alot of rad guitar shops.
Tone merchants has some really nice stuff, there pedal selection is the best in a 100 mile radius.
Obviously they have Friedman/Cameron amps and Friedman to build you the sickest rack/pedalboard.
But there are some other really sweet spots...
The Amp Shop/Bass Exchange on Ventura is a classic spot. played my first diezels there, their pedal selection almost rivals tone merchants.
California vintage guitars on van nuys has an impeccable selection of custom shop fender and gibbons, ALOT of them, and they have all the fendery amps.
Guitar center Hollywood actually has one of the best uses gear rooms in LA, and there vintage room ia really out of control, if you wanted that OG 57 fender, they have it there.
Wild west guitars in riverside has a really nice balanced selection of amps and guitars. Lots of PRS and plenty of divided by 13 amps, really big spot too.
There are really alot of little spots that are very boutiquey but in the end it's not as much the gear as is it the people there. If I can feel like I'm getting a really good deal I'm more into buying from a place.
There is the guy that charges msrp (Mesa boogie cough) and is stone cold will not budge on the price.
And there is the dude that makes you feel like you are getting a piece of your dream and they are going to work with you a little on the price and/or throw in a case and some strings or something.
I think that's by farthe most important thing.
I haven't forgotten about Chubtone, but I haven't been down there yet to check out his shop, but I have a good feeling he is one of the good guys...
