My Twin Valve head arrived the morning of Dec the 51st, that was three days in advance.
Cosmetic state is alright. just a bit grimey, but nothing that could not be sorted out with a slightly damp cloth and some elbow grease. No bumps or dents, just the expected swirls from age and normal use, not even scratches. I already knew from the seller pics that two of the EQ slider tips and caps were missing, but I have already ordered 4 new sliders from an american website (funny, isn't it) called

I also ordered some Series Six knobs for the sliders, but they are white, not black like the originals. I may get some black Strat pickup selector plastic tips to keep it in accordance with the original aesthetics, but that is a minor point I will see to later on.
The head weighs 13 Kilos. This is one Kilo less than my former Ashdown ABM 500 EVOII, which is perfectly alright for an all-valve head. Bear in mind that the lightest all-tube head I know of is the Mesa Boogie Prodigy Bass Four 88, that comes at 13 Kilos in a lunchbox format and pumps 250 Watts, but an Ampeg V4b that is powered at 100 Watts and weighs over 18 Kgrs.
The Twin Valveis built like a rhino. it is easily carried by two sturdy sleel handles that feel steady and reliable. I will shortly have an enclosed cover made by Hotcoves, in the UK.
here are some pcs from the seller. ill post better ones when I take my camera along sometime:
Fancy an expresso? He he!!
One of the extras this unit brings about is a switchable fan . The switch is placed at the back of the head. On wading through forums about the Twin Valve, I read that it gets hot from use, so I found this was really handy as the heat issue proved to be true. Trouble is that it is fairly noisy. I am not picky in this respect, but I might replace it in the near future with some of the modern and more silent computer fans existinting now.
Now, the sound. I only had the chance to test is alone at the rehearsal room. My heart sort of faltered when I switched from standby to on and I heard no sound but the fan's. Breath returned when I gradually started getting sound after a few seconds.
I tuned the EQ section on the GP7 graphic the following way: Flat at 50 Hrzs, a slight boost at 100 and 230 Hrzs, flat again at 500, +3 decibels at 1 and 2 Khrzs and flat at the top high frequency and started to play on my Sire V7 with the master pot at 1.
The sound is clean but thick, pushy, warm and authoritive. Using the passive imput, I could get clean headroom as far as 9 (will use 0 to10 scale for pot positions), then it started breaking up in a velvety way, but do not expect hairy overdriven sounds form it.
As I started turning up the master windows and drums started to rattle at 3. I do have to say that this thing is loud!
Could not turn it past 5,5. Still that can be misleadin when playing alone, and I will have to check out power and volume when the rest of the band is present.
The tone from this head seems to be exactly what I was seeking. Creamy, air-moving clarity; definition with warmth. Switching patches from SVT to slap on my Zoom B3 made my bass keep the pace in both situtions without sweating at all. I got the thump and weight note in the first case (quick enough in fast, tight notes passages), and the snap without harshness in the second (highs never got shrill). I have the impression that sound tends to be a bit scooped for some tastes, but I get as many mids as I want from tweaking the basses preamp or the B3's EQ. It' was just the versatitlity I was pursuing
All in all I could expect no more from a first contact, and I can't wait to test the head in a band context.
Hope this helps!
