Review: Sonic Express — Bradley Labs Iron Horse Combo

December 5th, 2013

By Chris Gill

If you own or have played a variety of electric guitars and amps, you’ve probably noticed that some guitar-and-amp combinations work better than others. If you’re really discriminating about tone, feel, and dynamics, you probably have also wished that you could mix and match the preamp, power amp, voicing, class configuration, and other features of different amps to build the ultimate individual amp for each instrument.

Over the years, amp builders have devised a wide variety of features that allow players to customize an amp’s personality to their preferences, but the Bradley Labs Iron Horse takes the concept of a user-customizable amp to an entirely new level. While not designed as the be-all and end-all of the guitar amp world, the Iron Horse offers an impressively vast tonal palette that players can tweak, tailor, and fine tune in remarkable detail.

The Iron Horse is a 30-watt amp with a straightforward non-master volume, single-channel design, featuring four 6V6GT tubes in the power section, a preamp section driven by two 12AX7s and a 12DW7, a three-knob tone stack (bass, middle, treble), a volume control, and presence and feedback knobs. User customization comes via 14 mini toggle switches on the front panel that allow players to select gain responsiveness, EQ curves, pentode/triode/ultra-linear configuration, 4/2/1 power-tube output, Class AB/A operation, 30/20/15/5-watt output, fixed/self-biasing, output impedance, and tube/diode rectifier settings. The Iron Horse combo we tested was equipped with a 12-inch Jensen C12K speaker, but it’s also available with an Eminence or JBL 12-inch or in a head-only configuration.

While the Iron Horse’s 6V6 power tubes will make many amp enthusiasts think “Fender Deluxe,” the uncommon quartet configuration (the only other amps with a 6V6 quartet I can think of are Jim Kelley models) makes the Iron Horse much more than that. The Iron Horse can certainly nail classic blackface and tweed tones, but the added punch of its 6V6 quartet allows it to also enter plexi and vintage Vox territory, albeit with its own je ne sais quoi.

The 14 switches provide a mind-boggling number of configuration possibilities, but once you’re familiar with what they do, it’s easy to quickly dial in desired tones and response. The process is as satisfying as working with a tech who is swapping components based on your comments, only much more instantaneous. Whether you want sag or tightness, enhanced upper or lower mids, fatter bass, or sparkling treble spank, it’s all there and accessible in seconds.

    Ya lost my interest at List Price $2,500.00. Looks nice bet it kicks ass But guys like me won’t never find out, you do know that America is in a recession. Job market has crashed unemployment is rampent, if a guy does buy it chances are it’ll be stolen in the first week. Breahins and home robbery is up 80 %.

    I just bought myself a Epiphone Les Paul Special II and now I want a kickass amp! I am looking at different amps, but this one just makes sense. Will the Iron Horse work well with this guitar?

    I purchase a Fender deluxe reverb reissue !968 and for the money it sounds great. Has anybody have opinions on this amp? Thanks. Clayton

    Mike why would you play a 150$ guitar with an 2.500$ amp? Buy a cheap transistor modelling amp first like line 6 spider or roland cube.. If you have a proper guitar and skills a “kickass amp” would make more sense. And in addition the variety of an modelling amp is higher cos there are several effects onboard..

    Since the author couldn’t think of many other quad 6V6 amps, the Dr Z Remedy also uses a quartet of 6V6 tubes. And its an amazing amp.
