I can’t think of a single recorded use of phaser before high-gain dirt though.įor certain synthesizer-esque tones like Ernie Isley’s Strat into a Big Muff into a Maestro PS-1A Phase Shifter then DI’d on “That Lady” then phaser after high-gain dirt is just what is required. Most of the time, if that one channel unmodulated blend scenario happen, you can actually increase the amount of modulation to create a more complex textures but without sounding tacky and without loosing the original voice.

This is also valid for modulating with other mod pedals like chorus or flanger. I guess someone could potentially create two differently voiced ODs one with phaser and one without and get something special out of it when blending the two in the amp, like the body of a thicker OD that normally looses the top end and attack (like tube screamer kind of pedal), and one with thinner, milder, more transparent OD with lots of top end and attack (like Boss BD-2 or Vick Audio Overdriver). Of course with the dirt pedal being there, you loose some of the dirt if you send the dirty signal to right and the clean signal to the left of the delay so that wouldn’t be a good idea unless the dirt is subtle like a mild transparent overdrive. I found the tone is more complex and I don’t hear as much of the repeated phasing cycles in my face. I then discovered splitting the signal and passing the upstream unaltered to the left channel of the delay, and the out of phase content to the right channel of the delay, then I combine the two channels in the amp (into the two inputs of my Reeves). That 74 reissue sounds really good! For the dirty tone, the tone gets altered so much that the repetition of phasing cycles seem to blend in especially with delay, but I found it becomes a bit too much for my taste, and too obvious repeating textures that in clean solo I always wanted something to vary or change the amount. This novel design allows the tubes to safely produce authentic power vacuum tube dynamic characteristics hundreds of times greater than their original design capabilities.Thanks Bjorn.

Without the phase shift and induction generation caused by hundreds of turns of wire and massive core iron to overcome, BK Butler's newly patented current multiplying DC coupled circuitry allows the 6SL7GT output driver tubes to directly operate into the constant ratio-reduced speaker load. This also completely eliminates one of the most inefficient and non-musical components in a typical tube power amplifier: the Output Transformer.
Therefore, the tubes are positioned to naturally and actively respond to the dynamic speaker load. BK Butler's Tube Driver BLUE technology places the triodes exactly where they should be: DC coupled through the output power devices to the speakers. Previous designs generally employed vacuum tubes in impedance-isolated preamp or pre-driver stages. Pics are from Butler website.ĭescription of amplifier design from the Butler website: Numerous reviews available online of the Butler 2, 3 and 5 channel implementations of this unique topography.Īmp is already boxed up and will ship from Chicago as that's where it was sent for reconditioning. It is quite powerful, producing 5 x 150 Watts RMS per channel 8 ohms or 225 Watts RMS per channel 4 ohms.
This is the most "listenable" amp I have ever owned and the sound was not inaccurate, just very well balanced and controlled. Ahead of listing, this amplifier has been inspected internally and externally by an independent audio electrical engineer and bench tested to ensure it meets manufacturing specification.

It was my favorite amplifier for many years, but a new set of full size planar speakers drove me to a dedicate two channel setup. I have had this amp in storage for a few years and decided it was time to let it go. Recently re-conditioned Butler 5 channel hybrid tube amp.
