The best boutique gear in terms of pedals is definitley Keeley, Moog, Zvex, MJM and RMC (real mcoy custom) for wha!
here are all the boutique pedals I currently own and often use:
01. RMC3 custom wha
02. Keeley Fuzz Head
I plan to eventually buy the Keeley Java Boost, the Keeley Compressor, the Zvex Fuzz Factory (for silly sounds) and MJM make some phenominal sounding pedals for the price! I also plan to get the Moog ring modulator pedal that they have brought out recently.
In terms of boutique amps, older Mesa's are amazing, so are Cornford, Matchless and Hughes and Valliant. These amps all cost serious money though but my favourite is the cornfords.
The conford Harlequin is ground breaking in terms of value and tone. If you ever heard 'watermelon in easter hay' by Frank Zappa, then that's the type of tone that amp can give you! the Carriera is even better than the Harlequin but it's too expensive for my budjet. Damn!
