This will develop a bit as we go on, but for now - here's what I'm using:
D’Addario:
If I own it, it’s strung with D’Addario. I use Planet Waves straps, capos and cables.
Yamaha:
For electrics – I currently, play their Pacifica 611 HFM into a pedal board that goes into their THR-100HD head and cabinet. I've even done live gigs with their THR-10 "practice" amp!
I got a good deal on the hardtail Pacifica and I really like the guitar! It's incredibly flexible tonally and as opposed to the trem guitars my double and tripple stop bends are in tune now! ; ). I expect I'll get a trem version as well and A/B them.
The THR-100HD is a monster amplifier. It handles pedals really well. Right now, I have it set to kind of a Plexi setting with the Master dimed and roll back my guitar volume for cleaner tones. Boost comes from the amp for lead.
For acoustic, I play their APX100 6-string and APX-700 12-string live with their THR-5a amplifier. I've done a number of shows where the sound was DI'd from the headphone out of the 5A!
PedalTrain:
I dig their boards. I'm using a Nano right now.
Xotic Effects:
The first stop in my guitar signal is their EP Boost with their voltage doubler for more headroom. Just a great sounding pedal and it's always on.
Boss:
I dig a lot of their stuff. Well made products. In my case, my secret weapon has been their FV-50H volume pedal. Has a small foot print on the board and I dig it. Their DD-7 delay is currently in my Effects loop - but that might get switched out with a TC Electronics Flashback II.
Guyatone:
I LOVE their MD-2 pedal - but my rig is stereo now - so I actually run it BEFORE the distortion for a low-fi kind of sound. I hope they make a stereo version at some point.
Dunlop:
I got turned onto the JHM9 - Mini Hendrix wah - which supposedly has the sweep of Hendrix's Thomas Organ wah. I love that it's so small and the sweep range is really musical.
QSC:
If I can't bring a full cab - I bring their Q-8 and it has NEVER let me down on gig. Next to gig bags - one of the best purchases I've ever made!
That's it for my current live rig. For other live variations...
ZT Amps:
Love these guys. Their Acoustic Lunchbox is an incredibly musical amp!
LR Baggs:
This is a another great company that makes great products! Their Session DI is a fantastic unit that I use as part of my full acoustic rig with the lunchbox.
F N H Guitars:
John Harper is a world class luthier and has the most terrifyingly encyclopedic knowledge guitar I've ever seen. He and Chris Fitzpatrick are building some really cool guitars.
Line 6:
A VERY forward company. I dig some things about their variax guitars. I've used every incarnation of their POD (except the Helix) and dig their M9 units as well.
Sonoma Wireworks:
I use their Guitar Jack as part of my portable iPad set up which also includes BIAS FX! The whole thing runs through my QSC K-8.
S-Gear:
For my money, Mike Scuffham's sim is still the most musical and best feeling I've encountered!
SooperLooper:
A Critical component in my live laptop based rig!
Atomic Amps:
I love their Atomic 18 and the 50 watt Reactors. They work great with modelers.
Radial:
This is a company that has some really great products. I just picked up their ABY box (which work great). When recording direct with my POD - I like using the Dragster to match the impedance of the pickups. I find the the volume roll off is a little more accurate. This was a really cool trick I picked up from a guitarist named Scott Peterson.
Apogee Duet:
Awesome audio interface for the pricepoint. Another component in my laptop rig.
Sweetwater:
Sweetwater is a great retailer. Their customer service is top notch and knowledgeable and they're not in the habit of letting me down.
