Old Ozzie Guy

Hi all, IV managed to find and purchase a new Gibson DC tribute bass, the last one in Oz.. it's on its way 2000klms to me. While Im waiting, IV ordered a few "bits" , and wish to change vol/ tone knobs. What size is Gibson pot shafts? Back in day were 1/4", but online I keep getting different responses.. Can anyone definitely tell me , in inches and or metric ?? Cheers

Thanks, that has been my experience with old AB ...I guessed at 25% drop in output..500 down to 375.. I was close....cheers

Thanks, I wasn't sure, been using valve gear for gtr since 70s..( for 6str gtr), and now back playing bass, so learning about class D..., Just got a Darkglass micrtubes 500, want to run 3 X 8ohm boxs .

Hi all, I have a question regarding output power and ohmage. With a 500 watt class D amp , with a 2 ohm minimum, what would amp output into 2.67 ohms, still 500 watts, or would there b a slight reduction? Am I confusing Class D performance with Class A/B, or am I just confused? Any thoughts b much appreciated.

Stand alone, the Ashdown is more of the tone I aiming for. Having owned a V4B ( old non master vol), with a Rat pedal, I was thinking PFs with a pedal to push. Thanks for your input.

Thanks J A , that was really informative..

I might add that I'm going for a very driven tube growl . 60/70s rock. Current using Darkglass Microtubes 500 V2 . I get a good tone, overkill headroom , but still not a valve ..

Hi all , has anyone had chance for volume comparison between Ashdown CTM 30 Little Stubby, Ampeg PF50t, Ampeg pf20t?? I'm playing in a trio (fairly low volume), I have a good sense of tones available from 3 heads , but am interested in perceived volume. Coming from yrs of playing 6str thru Marshall hd + quads, F twins, V AC30s ,ECT .I'm very aware that numbers of speakers, and their efficiency, impacts hugely the volume attained.. especially with all valve amps driving. So , with head set for similar tone and gain, thru identical speaker, what might the difference be ?( If any noticeable)? Thanks all

Hi all, I'm asking for comparisons between Ampeg svt210 av and Ampeg portaflex 210 Tone, volume differences? I'm looking at purchasing 2 cabs, I have tried svt210 and was impressed.. but wondering about portaflex ? I currently have a Ampeg Micro VR hd, so wattage is limited to stated 200 watts (although, apparently 260ish on a test bench) Cheers!

PS.. before everyone starts about " lack of bottom end",, I'm try for a tone reminiscent of Jack Bruce...(Cream) with limitations of an Ampeg Micro VR, and a hofner Beatle Bass... Pedals are a tech 21 VT, Darkglass SS comp , BBE stomp mini( set v low). Analogue delay (slap), Both hpf fx loop, Im looking to add a good gate there soon .

Maybe I can explain myself abit better. I have a Boughton active -12 db to b set 45 Hz, then I have a gob -3db passive set to 70 hz, Therefore "cut off" begins at (approx)70 hz at 3 db per Oct, while at 45 hz increased slope of 12 db per Oct.. soft then harder knee.. I hope this explains.

Thanks Mate. PS. U don't know of a gate pedal with more control parameters than threshold..ratio ? ie attack and release

A friend of mine had a Vox 130? watt valve hd circa late 70s?.? Not sure exactly, but it sounded huge with 2 JBL d130 15s... And weighed lots more than F b/man 100 or Marshall bass 100. I'm pretty sure it was classA/B too , not classA (AC 15/30) is ac50 class A or a/b ?? Again, love your rig , deserves to b gigged!!

Welcome...errrr.. drooling over the Vox hd and box.. worth a small fortune in Australia..
