A little more on the pairing of each of these heads with my EA cabinets. I know I am starting to build an EA collection.....
First focusing on the PRO, suprisingly I can get my VL108 stack to clean volumes I honestly didn't think it could achieve. Although this small stack is really my small practice rig and using the DOUBLER at home with it and on some other stuff I talk about later.
Using the PRO with my VL208 stack is pretty pillowy as you might imagine, it has more of an old school type tone. It sounds really good but for me it's not my optimal rig. The PRO with the NL210 sounds really nice just the right amount of top end without being to brittle until I start to push it to it's max. The best combo with the PRO is a VL208 on top of my NL210 this seems to have the perfect balance between bright and snappy while providing a nice full bottom when really pushed. Since this type of volume is only neccessary for a few very large clubs that I play and some big outdoor events in the summer the added schlep of two cabs and the larger head should be no big deal. If I was playing 2 or 3 gigs a week needing this kind of power I'd probably consider a 4x10 cabinet but that's not the case for me.
Most of the corporate stuff and small clubs I do work perfectly with my NL210 and I think I'll be able to interchange the Doubler and PRO on these types of gigs. At least in the beginning it will be nice that the Doubler sneaks into the accessories pocket of the PRO bag. That will allow me to do some A/Bing on site.
The Doubler is the best Upright amp I've ever owned and paired with a VL208 it is tone heaven, I don't think I'd be inclined to use anything else unless I am playing with a trio in a really small restaurant and in that case a single VL108 will do the trick.
The VL108 stack also works out really well with the DOUBLER for pit work. I ussually do about 3 or 4 productions a year, thus far I've done 1 with this rig. And it's super small foot print helps out in the tiny pits I tend to be stuck in. The tower allows me easy access to the amp controls and getting great tone at very low volumes.
The DOUBLER on top of my VL208s provides the best P bass tone which I pull out on some gigs where I'm doing all motown or classic rock. I don't think the PRO will replace that set up as that stack get's pretty loud on it's own.
A little more on the EQ for those that are not familiar. First off it works the same way as the older IAMPs and is also similar to a Millenia TD1 for those that are familiar.
The lows has a frequency slider from 40-180 hz., the low mids has a slider from 180hz-1khz, the high mids slider is from 880-5k and the highs from 1k-5k. In addition the two mid bands have an adjustable Q or the width of the frequency that is effected. It is very nice that the cut boost knobs measure in DBs which is nice for reference. There is also an on off for the EQ so you can dial something in and then A/B to the head flat or to one of the presets. This thing is powerful and quiet!
I had touched on the audio taper with the doubler and the PRO is no different this head seems to put out clean clear tone all the way up the gain and master outputs. Unfortunately I do not have a cabinet that can come close to handling both the pre and master at ten to fully test that out. Honestly baseed on my experiences I don't think I've ever owned a cabinet that could take all the power with this thing dimed without exceding the cabs capabilities, but I'm only guessing this....
So it's not a micro head, it's certainly bigger then the MB F1/ F500 and a little bigger then a LMIII but these heads like the DOUBLER suffer from not being able to always deliver that monster power requirments that we all have at some point. This head fits right in the middle, it's small, light and provides the monster output capabilities of a huge Glock HR, Aguilar DB750 or Carvin B1500.
Thanks a lot for breaking it all down -- very interesting!!!
