Yes, the circuit was custom build for this bass. Stunning looking and performing bass that needs a permanent home Peter

Excellent news Stu The bass is provisionally sold. Peter

The pups are Alan's RFB Hum-buckers so yes MM style. This is drawn from another thread but written by myself: [i]I've been meaning to get around to producing a short post that illustrates how a filter based pre-amplifier works. It really isn't rocket science, it's just a different approach to the usual 2/3 EQ and you can't really relate to one via the other imo. In addition to a volume/blend knob basically you have: 1. A Low Pass Filter The ACG01 fitted to Alan's basses has one per pickup. The ACG02 retrofitted to a (cough) few of my basses has just the one. Imagine it's a bath tap. When the tap is shut it's leaking just low frequency sound, about 20Hz if I remember correctly. As you open the tap it allows progressively higher frequencies to be added to the flow. When the tap is wide open it's allowing everything through from the 20Hz right up to 3kHz. There's another 'little tap' on top that let's through a little extra just at the cut off frequency i.e. when the big one is shut that'd be 20Hz and when it's wide open 3kHz and wherever it's set in between. This allows you alter the shape of the frequency spectrum. This knob I will call the resonant peak boost, cause that's what it does. The low pass filters are always letting sound through. This tone is what I'd call the 'meat'. It's always there. The High Pass Filter can be shut right down like a 'non leaky' tap. I'd describe this as the 'gravy' in that you can add some if you need to but it's not essential. If the tone through the low pass filters up to 3kHz is good for you you can ignore the high pass filter. 2. High Pass Filter It's not so easy to demonstrate what it does because it's not possible to listen to it's output in isolation like it is with the low pass 'jobbies'. It works in the same way but the other way around. When this (hot) bath tap is shut it just leaks the very highest frequencies (sizzling) and as it's opened progressively lower frequencies are added in right down to about 1kHz. So you can see that it overlaps the low pass filter when wide open with it's lowest mids lower that the low pass filters highest mids. The top knob on this filter isn't a resonant peak boost (this is important) but a straight boost with minimum boost being zero. So it can effectively be turned off. Here's how I go about creating my available range of tones: 1. Isolate high pass filter by shutting down it's boost and removing it from the tonal equation. 2. Blend to the neck pup and using low pass filter get the tone I want from it (I think more 'P' tone here). 3. Use the resonant peak boost to shape the tone further. 4. Blend to the bridge pup and repeat 2. and 3. above to get tone required (I like some jazzy honk). 5. With the 'meat' sorted middle the blend and introduce higher frequencies (gravy) where you want them and at the level (amount of boost) you want them. 6. The above is all done as preparation. For tone when playing just use your blend to go from neck to bridge pups and access a whole seamless range of tone. So why bother? A normal 2 or 3 EQ pre allows you to tweak the colour that that individual pre-amp creates. The ACG filter based pre-amp allows you to create the colour itself. That's how I see it. [/i]

The neck is indeed asymmetric, being a bit like a bass clef in shape with the thicker part of the shape at the top. fret access is good unless you play 'thumb over board' in which case a single cut makes little sense Peter

I know the feeling. I wish I could realistically keep mine even if only as a seldom played ornament. Peter

Hope you're ok mate [/quote] Hiya Nik, Alan and all I'm well thanks, Uni finished and looking for a real job as someone saw saw fit to give me a social work qualification I've got a job offer at ASDA, part time, 5 days a week, 4 evenings and every weekend at £6.15 an hour (desperately looking for something else before I start in a week). Got an interview for a 'Christmas seasonal job' (not Santa) today. Band teetering and needs new blood. Lady and I very happy. Busy with biking too. Pedro

Waves hello - not been around these parts much I know I'm selling my ACG Harlot. About a year ago I switched to playing 5 string and I'm not playing this absolutely stunning bass. If money weren't an issue I'd keep it but I need the cash to pay for one of Alan's Graft range (5 string Gallus) to keep me in ACG-ness while waiting for my headless Gallus to be built. A winning lottery ticket or a job offer would save me selling this bass This is a stunning example of Alan's work which really is up with the best. I've spent time with Alan while he works and his attention to detail and level of workmanship is remarkable. Here are some photos Alan took on its completion. It is in immaculate condition. I'll take some photos myself this week. It has a rich ebony fretboard with 34" scale. Front and headstock facing is Ambonyna burl. Core is Hondo mahogany and the rear is a beautifully contrasting sycamore. Spacing at the bridge is in the region of 18 to 19mm. The neck is flame maple and Macassor ebony with Macassor ebony to the rear of the headstock and on the cavity cover. The pre-amp is an ACG 01 filter based unit with the later upgraded frequency ranges and coil switching for both of the RFB humbuckers. 18v supply to the pre. Bass comes with a Hiscox hard case and Schaller straplocks. The bass is in Kendal and viewing is welcome. £950 - no trades

[quote name='robocorpse' post='897498' date='Jul 17 2010, 07:01 PM']Why does this make me really angry that someone bid it up and up and up, then doesn't want it? now the percieved value has risen - again - and everyone else who has a Status under the bed will automatically think it's worth minimum £1000, unlike the handful that have sold on ebay in the last few years for between 500-800... Seems as soon as I actually had the dosh to buy an all-graphite Status, they get bumped up again, and the likelihood of getting a good deal is getting near impossible now. I bet the guy who got the worn S2 off ebay last year for £450 is laughing his head off right now.[/quote] It might make you angry (you actually make yourself angry) but why shouldn't somebody be allowed to bid on something 'in the moment'. Seems to me you're easily angered

[quote name='crez5150' post='869893' date='Jun 17 2010, 02:05 PM']String spacing is from the centre of one string to the centre of the next at the bridge.... 16.5 seems a lil narrow.... Status normally 18.mm or 18.5mm on 5 stringers[/quote] Mines 15mm, and I wouldn't swap it for larger. That's one sweet bass though and only just down the road. Just as well I've no spare money.

Most exceedingly lovely that is
