A/B ing amp heads

[atf]

Take a Vox nightrain (v1) and an Orange Tiny Terror, A/B them through a Vintage 30 412 or 212 and you have a plethora of tones.

I use EHX tubes in my NT so it's super bright, but through a v30 cab it evens out and the thick mode sounds like a Bogner ecstasy red pedal. Add a maxon and a SD 1 to tighten them up and you are good to go.

Anyone else A/B amps/head? What were your results?

Re: A/B ing amp heads

Are you referring to using an ABY pedal in front of the amps and going into both sides of a stereo cab or two cabs at the same time? If so, then yes; this is how I play live most of the time.

Yes. I'm sorry I meant ABY. But I was also thinking using one head for cleans let's say and switch to the other head for dirt using something like s tonebone tube switcher

I used to use a Blues Deluxe combo for cleans and a two channel Dual Rectifier for dirt, but never two heads into one cab.

Re: A/B ing amp heads

it can absolutely be done but you need to make sure both heads always have a load (assuming tube amps). if you are running each head into half the 4x12 then you can use the a/b box to switch between them. if you are using the same speakers for both amps then you need something like the radial tonebone headbone vt as well as a way to split your signal to both amps

Also have to watch the load. My stereo cab is 8 ohms on each side and doesn't have a mono setting. You either use two amps or half of the cab.

Re: A/B ing amp heads

I have experimented with using two amps (each through their own speaker cabs) as a clean amp/dirty amp set up using a ABY switcher. Maybe I wasn't doing it right, but I was not real happy with the results. Through the switcher neither amp sounded quite as good as it did alone. There seemed to some unavoidable signal loss. Then there can be more, noise problems, and ground loops, and phasing problems. I know lots of people make it work but it does not appear to a simple thing. For me, a good channel switching amp was a better solution.

Re: A/B ing amp heads

i used to use a twin and jcm800 half stack for clean and dirty respectively. simple a/b (no y) box and i didnt have any signal loss issues. guitar->sd-1->dd2->a/b->amps since they were never on at the same time, i didnt have to worry about phase and noise didnt really seem to be an issue although i always kept a ground lift plug in case the power at the club was wonky. if you use two amps at once then obviously you need them in phase and passive aby switches do send less signal to each amp but these days there are lots of good quality active aby boxes that dont have the same signal loss.

i only bring one amp these days though, usually too much hassle to deal with more

Fulltone makes the True-Path ABY. It's an active unit. I don't believe there is any loss from the split and whatever circuitry they are using is pretty transparent. It has switchable phase, ground lift and switchable output buffers. I use it mainly to split and switch between the normal and treble inputs of a 4 hole Marshall rather than jumping. I know that Radial gets most of the play but the Fulltone is a nice box.

the fulltone unit is fantasic

I've been toying with the idea of buying NT15 to accompany my TT. They seem like a perfect mix on a paper.

How well they blend together? Are you able to get great cleans out of them with added headroom?

I used to run two amps because for some reason I couldn't figure out the clean channel in my Jubilee. The tone was pretty good, but carrying all of that stuff was just too much trouble. I finally figured out the Jubilee clean channel a couple years ago, so these days I emulate my old dual amp rig with a Loopmaster Clean / Dirty / Channel switcher.

The vox has very good and loud clean tones and the crunch sounds good too.Its a lot louder and brighter than an AC15 to my ears.Plus with a three band EQ you have more options to shape the sound.

In terms of transition from clean to dirt, I don't think it's that smooth, they are slightly different tones, the NT is a vox that has a voxy crunch screams when pushed, but the TT is more fatter and creamier. Having said that the tonal options for a lot music between the two are there and adjusting settings is easy too.
