New Amp - More Diversity

Since the cost of getting my Marshall head fixed was going to be about the same to actually buy a replacement, I decided to not get it fixed (but I will at some point) and just get a new amp.

The candidates where (due to budget)
1. Crate Powerblock
2. Roland Cube 60
3. Vox Valvetronix AD50VT

Line 6 was left out because I don't like their modelling. Too digital to my ears.

The winner by a mile is the Vox. I was talking with the Korg rep at a local shop about these amps and he had mentioned that the guy who designed the "Valve Reactor" poweramp in those things was retired from Marshall and Vox approached him.

I can't believe the sensitivity of this amp. It reacts so well to picking dynamics as well as rolling back in the guitar volume (which I do a lot). The models are the most accurate that I've heard out of all of them. My favorite models are the Boutique CL, UK 70's, UK 80's and US Highgain.

The effects are really nice and easy to set. There's not too many of them either, pretty much everything I'd use if I wanted to; delay, reverb, compressor, phaser, flanger, chorus, tremolo, auto wah and rotary. Some of them are combined with another but from what I can tell from reading the manual one can be disabled leaving the other. It would be nice to allow mixing/matching of the different effects, but then that would be a price increase and probably out of many people's range. Not being able to do that doesn't bother me since I'm using the reverb and chorus/reverb pretty much anyway right now. Tremolo or Rotary may have some use too.

As for the other candidates; the Roland is nice, but a little too digital sounding still (compared to the Vox) and the picking dynamics aren't as crisp as I like and a couple of the models didn't quite sound as good as the Vox. The Powerblock simply ran out of clean headroom. I couldn't get a nice clean sound at very high volume. Still, it's a great little amp. Standalone the thing sounds great.

The speaker in the Vox is a Celestion, at least the tag hanging from the MV says so. Not sure which model other than it was made for Vox. Sounds really good. The sucker can move some air that's for sure. The variable wattage control on the back is an awesome feature. With this, you can set you amp models and channel settings to have the levels way up there, letting the thing breathe and open up, but keep the actual volume down to say a 5 watt practice amp, or in a small room, up to 30 watts. Playing a gig, turn it all the way up. It's loud.....real loud, and sounds really really sweet that way. While I was messing with settings in manual mode last night, I had the US Highgain setting and just about shat myself after dialing in a sound that was rediculously close to my Marshall, but at a much lower volume.

Band practice is tomorrow night so I'll know more in how it performs in that situation but I have no doubt it will be fine. If I need more oomph, the speaker out allows me to hook it up to another cabinet.

For what my band is doing right now, this amp fits the bill with all the diversity in it. Doesn't mean other amps are out of the question. A Mission Aurora is still on the list, either at the end of the year or next year. The budget had a big influence on what I could spend, and the Vox is the best bang for the buck when it came to that.

Very cool EriK..... i still have not made a trip to the post office for you-(later today i had better get my butt there)

But let me know if the vox fades away in sound and balls at a band practice or not... that is a common complaint of lIne 6 users and i hope the Vox is better

I'll be sure to post an update on how it does tomorrow night. If my wife's reaction yesterday was any indication, I don't think there'll be a problem...lol. She was with me because I wanted "audience ears" to give me an opinion. At one point I decided to turn the wattage setting all the way up to 50 watts but I had the MV still at half way up (noon) on the US Highgain model. As soon as I struck a chord I thought she was going to jump out of her clothes right there....LOL. The look on her face was a mix if surprise and "OMG!!!!!!"......LOL. Not to mention she jumped back a few steps. And it didn't fart out either. I did the same thing with the UK 80's model and got a beautiful "KERRAAAANGGG!!!" out of it. :)
 
Re: New Amp - More Diversity

The Vox is one of the few that handles like a real amp. Like you said, it responds correctly to volume knob manipulation, and picking dynamics. Besides the Zentera, I agree it's the clear winner in modelling. It's "right" on the front end where it matters. It probably works right with any front end pedals, too.
 
Re: New Amp - More Diversity

I've been told that it works well with pedals out front but I haven't tried it yet. Tomorrow night I'm going to try out my modded SD-1 and another booster to see how it takes them, and my wah. I'm not in to auto wah much so I'll use my Crybaby instead.
 
Re: New Amp - More Diversity

I tried a lot of the digital modelling stuff and the Vox was the winner hands down.

I have the Vox VTH 120 Stereo Head as you know and still love it....
Yup, I remember you have the 120 head. GC had one there but I didn't dare plug in to it. They had the 60 and 120 combos too. Nice amps but out of my budget or I would've ended up with the 60 watt combo probably. But then again, I've got enough OD, distortion and booster pedals to put out front if I want so no need for those models.

I can't wait to crank this sucker tomorrow night. :D

Nice to know from someone with ears like yours. Maybe one day we'll see a Celtic Franklin or Edana model. :banana: :D

Haha! My ears are old and damaged. I'm moving into tweaking amps by the feel of the sound pressure on my skin.... :eek13:

:) But, I did like the vox. A 1x12 valvetronix is a great grab and go package. Lots of tones hiding in there.

That's what I like about it. I can put my wah and either an OD or booster in a bag and go. Even with my Marshall I had only a delay in the effects loop and an overdrive out front but with this thing I don't need anything out front really, but I plan on putting the wah out front and that'll probably be it. After using it once at practice I'll probably change the tube to an EH12AX7 since I have a few not being used at the moment. Just gotta find where they put it in these things. :6:

Hi ErikH
I've got one of these amps (the Twin 12" AD 100) and just love it but with the effects when doubled up you can not switch one of them off unfortunately the effects are as marked on the dial.The speakers are Celestion 70/80's re-voiced for modeling amps, but an upgrade to a pair of Celestion G12 Century Vintage really made this amp Rock!. There is a great site fore tips etc it also has a load of patches(great to get one in the ballpark then tweak to taste if you're feeling lazy)

Re: New Amp - More Diversity

Foeburner: Grab your guitfiddle and try one out. :)

Oldslowhand: Thanks for the tips. I knew the combined effects weren't switchable on/off via the switch but if I want just phaser and no compression, I can do a little editing and take the compressor completely out of it. That's what I meant. I thought they changed the speaker at some point. Glad to know it's still the 70/80. It sounds great. I looked at the 100 watter but it's open back and I like the sound of closed back.
 
Re: New Amp - More Diversity

I have the Vox ToneLab tabletop processor, and I love it. It uses the same technology as their Valvetronix amps. I'm not really into modeling, but the variety of tones from this thing is amazing. And it does in fact work well with stompboxes. I put gain effects in front of it and modulation and ambience effects after it, and it always sounds good to me.

I never thought of that cool!

However I did close the back off but thought it sounded better open To each there own

The ToneLab is nice, but still a little different from these amps (The AD15/30/50/100), meaning it has more in it. What's in the ToneLab is more in line with the 60 and 100 watt blue versions. There's more amp models available in those, pedal models, a few more effects, and more programmable presets. I don't think the ToneLab has the Valve Reactor technology like the amps, or does it?

Another thing I did find out is the bit processing in the AD15/30/50/100 is 24-bit vs. 20-bit in the 60/120. That's interesting.

I haven't tried the editing myself yet. Been to busy playing with everything else...LOL. I love this thing.

If I got the 100 watter I probably would leave the back open too, if anything to help disperse the sound around a little bit. I could probably do something like that with the 50, make a half-close back board to put on there, but I may end up running through my 4x12. I'll know for sure at practice tonight. If not, then I'll just use the cab for bigger places and get an amp stand to angle it a bit.
 
Re: New Amp - More Diversity

There is a 12AX7 in the power amp stage of the amps. This is from the manual. Yeah, it says the same thing in both manuals but just for reference.

"While much of the tone creation and shaping carried out is done in the digital domain, the Valve Reactor power amp is 100% analogue. The resulting journey your guitar’s signal takes through the analogue world of the power stage plays a major role in providing the all-important feel and tone of the original amps we modelled. The Valve Reactor power stage is, to all intents and purposes, a bona fide valve (tube) push-pull power amplifier, but in miniature. It utilizes a 12AX7 (ECC83) valve (a dual triode device — meaning “two valves in one”) and is equipped with an output transformer, just like a “real” valve amp.

The power amp output signal is designed to “read” the constantly changing impedance curve of the dummy speaker circuit system and feed this information back to the virtual output transformer — just like an all valve amplifier does. This information permits the behavior of the valve stage to vary with the speaker load (impedance), which is another important part of “real world” valve tone."

If you haven't tried any of the amps, you should, because they sound totally different from the ToneLab. I tried the ToneLab too and didn't like it. It reminded me of the PODxt Live.

The difference with the ToneLab is the Valve Reactor technology, although the same as what's used in the amps, is encompassed in the amp model selection since there is no actual power amp in that thing. With the amps, the amp model selection changes the preamp AND the actual amp's power amp accordingly, with the 12AX7 sitting in the power amp section. The system diagrams of each shows this and is exactly what the Korg rep told me last week when I talked to him at one of the stores here.
