Plugging a bass into a Kaoss Pad carries a small but worrying risk of causing the Universe to implode, a bit like running the Large Hadron Collider.

[quote name='bassman7755' timestamp='1399806222' post='2447785'] In point of fact you could use a transformer PSU with a class D amp but it defeats the point somewhat since the primary design objective is light weight and efficiency. Conversely you can use a switched mode PSU with a class A/B/AB with some additional trickery that allows them to vary the supply voltage in line with the signal thus overcoming the inherent inefficiency of A/B/AB designs operating on a fixed voltage. This is the so-called "class H" design used in earlier light weight PA amps such QSC PLX range but this design seems to be losing ground to class D designs these days. [/quote] [quote name='Beer of the Bass' timestamp='1399806646' post='2447796'] The power supply and associated mains transformer are a separate issue from the type of power amp used. Usually Class-D amps and switch-mode power supplies are used together, but there are exceptions. The older Acoustic Image heads had a linear power supply with a toroidal mains transformer powering a Class-D power amp and were surprisingly weighty for their size. The Markbass LMII uses a lightweight switch-mode power supply with a class-AB power amp. [/quote][color=#282828][font=helvetica, arial, sans-serif] I knew this would come back to bite me! Yes I am aware of this, but couldn't be @rsed to go into the full details. My bad! [/font][/color]

Oops double post.

Mind you, there is a 1960 stack-knob Jazz on his website for £17,995.

Although many will love this bass, it does nothing for me. Maybe I would feel different if I tried it...

December is looking very quiet, and New Year's Eve is still available.

[quote name='LukeFRC' timestamp='1399758636' post='2447465'] for the stupid amongst us... can you explain the difference? I know that AB or D (or H i've seen somewhere) is one bit they can save weight on, along with the power supply... but apart from that I'm a bit uneducated [/quote] You can find an explanation [url="http://en.wikipedia.org/wiki/Class_AB#Class_AB"]here[/url]. The practical benefit of Class D is the lack of big heavy mains transformers.

Played with my pop covers band at a Royal British Legion in a garrison town. Very few people in attendance, but one bloke in a Sex Pistols T-shirt kept putting punk tracks on the juke box. I was astonished when the Pistols' song 'Bodies' came on - if you've never heard it, have a listen to understand why this was weird to hear in a RBL. Anyway the gig was a proper tumbleweed job, but the ents secretary liked us and wants us back. And the strained muscle in my right arm didn't adversely affect my guitar playing, though I did have to get the drummer to help me with my guitar amp.

They are a business seller and have the bass advertised for £695 on their own website: http://shop.musical-money.co.uk/guitars/3127-1983-jv-squier-by-fender-precision-bass-guitar-fiesta-red-with-hard-case.html

I wonder:[list] [*]How many speculative emails they get each day; [*]Whether someone has been given the job of answering them; and [*]What proportion of those enquiries would turn into sales that would not have happened if they had gone unanswered? [/list] IMO those are the questions that GV (or any other shop with an online presence) needs to consider before setting an 'email response policy'.

[quote name='Lozz196' timestamp='1399713941' post='2446857'] No dealings with either, but my advice would always be get the one your hands like the most, the one which playing brings the most smiles. [/quote] This. Only buy a bass if it makes you want to keep playing, to the point where it says to you, 'You would regret going home without me'.

Not sure if this has been linked elsewhere but I just read this: http://www.iguitarmag.com/news/2014/05/wilko-johnson-undergoes-cancer-surgery/

[quote name='dood' timestamp='1399466998' post='2444489'] Yep definitely not a problem with the cabinet. Your bass pickup is picking up mains noise from your amp sat on top of the cabinet. The tweeter in the cabinet allows you to hear that noise more clearly. It's completely normal and some basses will pickup more noise than others. You'll sometimes get the same problem playing under strip lights with basses with non humbucking pickups. So nothing is blown by the sounds of it. Your bass is just very good at picking up noise in the room and your cabinet is very good at reproducing a wide range of frequencies, including those with noise in. [/quote] This supports my theory that the concept of tweeters in bass cabs was invented by Satan

I've visited a few times and have no complaints.

[quote name='VTypeV4' timestamp='1399483225' post='2444702'] I wouldn't mind some greater capacity ones (or two, three etc) in an attempt to circumvent a repeat incident tho. [/quote] If you are going to upgrade your caps, don’t go for bigger values, as this can cause your rectifier diodes to fail. By all means go for higher working voltages though, for a wider safety margin.

Finally got round to replacing the trim-pot today. First removed the driver valves from the rear circuit board. Then undid the rear panel connectors and ribbon cable from the DI board and popped it out: Ddi the same with the main rear circuit board: Removed the five fixing screws from the board. Had to move the transformer to make enough room for all the sockets to clear the back panel. Twisted the board up, removed the old trim pot, and cleaned up the holes: The new trimpot was a bit small so I put the outer pins in vertically and left the middle pin sticking out: I salvaged a leg from the old trim pot, soldered it in place, and joined it up to central pin on the new trim pot: After everything was back together except the top cover, I set the bias again. I had noted the resistances between the pins on the old trim pot, and set the new one up the same, so it didn't take too long to set it right. The voltages still drift a bit, but no more than a millivolt or so, and it's much easier now to tweak the bias without it suddenly going into panic territory. While I was in there, I realised the cooling fan would be much easier to replace than I had thought, so I noted the details for future reference. Looks like you can only get it from America anyway, but I've found a close equivalent on eBay - a low noise job for linear amps. A couple of hours well spent
