When you buy a guitar pedal that is supposed to give you a particular tone or amp model like the Fender pedals which are supposed to replicate the Fender Bassman amp or Reverb amp, does the pedal override the settings on the amp you are using it on? So, all tone control is coming from the pedal? Or do the a,p settings effect it as well? This is besides the pick up and or tone setting that you have on your guitar. |

the whole rig is one instrument. guitar with its pickups, strings and wood's sonic properties, amp (including any preamp signal processing) and speaker(s), they all together make and colour the sound. you can't rely on one single element in the chain to supply the sound you're looking for.
a lot has been promised by the modelling amps and i'm still interested in what they can or will be able to produce. but so far, and it's been some 10 years now, they still can't match the sound and feel of a tube (valve for the brits) powered amp. the dynamics of tube signal distortion still haven't been solved in modelling amps/effects. i believe that anything that exists in the real world can be modeled in a digital domain simulation and put into a working model, a replica of the real thing. why it hasn't yet been properly done in this case i don't know. i doubt it has to do with latency which is present in digital signal processing (obviously the digital models aren't as efficient as the real thing) because the technology keeps coming up with higher clock speeds and other improvements of efficiency.
a few years ago when i was looking for a sound i'd be content with but i couldn't find anything, i.e. not the right sound/price range/power... i ended up building my own amp. it's a version of this schematic; a single-ended EL34 tube in the power amplification and two ECC83s (that's three preamp stages plus one cathode follower), the schematic is modified to my own liking and due to availability of parts, this with a help of simulation software which shows how modifications of the circuit affect the output signal, and then some live trial and error testing. the output is wired to a Celestion G12H speaker.
i wouldn't want to encourage anyone to go play with high voltage on a whim, doing this can be fatal. as in you really get killed. but if you are truly interested and confident about your safety conduct and have some knowledge of electric current or are prepared to learn some (i had to), you can check and research this website and the links from there. of these Aiken amplification is an excellent resource. you can hear some examples (though live testing is the only way to compare tube amps with each other and especially to digital stuff) here http://ax84.com/?pg=legacyprojects&project_id=hioctane
the benefits of this are plenty - you get to build exactly what you want (though first time projects should be simple designs), whatever sound you're after, whatever power you're after (some are even building tube amps for the "bedroom level" sound volume), not to mention it's waaaay cheaper than some boutique tube amp, even cheaper than some solid state amps that boast high wattage like 60W but get totally blown out of the water when paired with this poor little 5-watter.
when i have some more time, hopefully next summer, i'm making another one, i was thinking clean preamp section + poweramp distortion, and i'm still undecided on the single-ended or push-pull output stage (if you check that website you'll know the pros/cons of each). i'll be posting the progress of that and maybe some soundclips (if anyone has any music wishes and if i'm able to play them) when i get to it.
i'll stop derailing the thread subject now and say that i'm looking forward to anyone's attempt at a well balanced and nicely working combination of a multieffect or some sort of modelling preamp driving a tube power amp.

Newer amplifiers have a preamp-out and power amp-in, which is
a line-level effects loop. If you plug the pedal into the
power amp-in, you can bypass the amplifier's tone settings.
The Boss Pedals are not designed to do this, however.
If you plug into the guitar input, you will still use the
amplifier's tone circuits.
You will always need to make some adjustments, I don't think
you can get totally away from the "colouring" of your amp.
Please tell me more. I have seen these pedals advertised,
and I have an early version of this in a multi-effects unit.
Have you tried one? Are you considering buying one?
For what purpose? |
