Just play the D an octave above. Nobody in the audience will be able to hear the difference.

They're great amps which sound mighty through virtually any decent quality speaker. Mine sounds fantastic through my Monza. Slightly too big to look right, but hey!

Not playing, but I fell asleep during a dive in the Red Sea once - Woodhouse reef, just drifting along in the current 15 metres down. Someone else's depth alarm woke me up.

2 old-time banjos, 3 tenor banjos, 3 bouzoukis, 2 guitars and 2 Weissenborns. That's the middle shelf. There's an accordion on the bottom shelf too.

According to the manual the amp expects a momentary switch and doesn't mention a latching switch, so I assumed that wasn't an option. After I posted I read the data sheet, and you're right - connect D to Q bar. The switches I have are DPDT so I think I wire one side to the output and one side to the LED circuit. The other question is what to do about syncing with the state of the amp. The Bright Onion has a sync switch which changes the LED without affecting the output,

Does anyone have any thoughts, or maybe even a circuit diagram, for adding a status LED to a momentary footswitch? I have a pair of momentary footswitches that I'm using to change the channel and mute on my EA Doubler but some indication on the switch would be handy. I could buy a dual footswitch pedal from Bright Onion for 65 quid, but it should be possible to build one for less. I was obviously thinking about this problem a while ago, because I've just come across a couple of flip-flop ICs (SN74HC74N) in a drawer, and I can't think of any other reason I'd have bought them. I found a schematic which seems to do what i want to do, I guess I use the footswitch for the clock and just connect D to VCC instead of having another switch? http://sullystationtechnologies.com/icdflipflop.html

I've recently put this together to allow me to switch between double bass (using the EDB1) and bass guitar (the DHA VT1 Pro). The strange blue lump is a box with 3 momentary switches and one locking switch which I built for a Roland AC60. I'm using half of it to change channel and mute the amp, an EA Doubler. I really need to build a 2-switch box in a 1590A to get the size down a bit. I could use both amp channels, but I only want one tuner, compressor, and high pass filter. EDB1 runs on internal batteries since the power bank only has one 12V output, though I guess I could run the DHA at 9V. Cables are a mess. What do people recommend for a more compact solution with the right lengths? I'm wary about the solderless ones because we have a guitarist who has no end of trouble with them, but maybe that's because he is a guitarist. The Becos is an amazing compressor but I'm having a tough time finding a power cable with a long enough plug. Most are too short to work at all. I have a Maplin one but it falls out occasionally and I've taped it in place. Also, if anyone has a flip-flop circuit to fit an LED to a momentary switch I'd be very glad of it.

That's a good endorsement @Al Krow. Does the Core octave have the same 'Range' capability to only operate on lower frequencies that the OC5 and OC3 does?

I had a 1/2 size for a while and it was OK to play and very portable, but sounded puny against a 3/4 .

Bad news for skiffle fans. "Down the Mississippi to the Gulf of America" doesn't scan.

For a minute there I thought the Burman Pro 4000 had one, but it's only the guitar heads like the Pro 2000 which do. I misremembered. Although there is no reason why you couldn't use a Burman guitar head for bass, if you could find one. Plenty of people did back in the day.

I was told that it used to be the case in the orchestral world that left-handed double basses, and other strings, were not permitted in orchestras because it spoils the visual effect of having the bows all going the same way at the same time. If you were left-handed, you learn to play right-handed regardless.

I'm using an RB Boss Shelf which I got online from Wicks. Industrial grade, free standing and not fixed to the wall, although it does have a couple of wedges under the front feet to just angle it back slightly. You can put the two middle shelves wherever you like.

A friend has one. Fantastic for rounding up stray dogs.

We have a new acoustic blues jam in Ipswich, every last Wednesday of the month at The Duke, Ipswich. It's run by Tim Ainslie (guitar, vocals) and Adrian Day (harp, vocals) . I'm not normally one for jamming but since I have a high regard for both these guys and play in a band with Adrian, I went along last week. Acoustic instruments only, no drum kit (there is a Cajon), no electric guitars and the pub's Yamaha piano. Adrian provides a low-volume PA and some DI boxes. I took my double bass. Another bass player eventually showed up with some kind of pseudo-semi acoustic thing, which I didn't recognise. Both basses sounded OK at low volume through the PA. Usual format: Tim and Adrian did a few songs, then rotated the line up through the 5 or 6 guitarists, 2 keyboards and bass players who put their names down on the list. The atmosphere in the pub was great, quite a few people had come along to listen and chat, and were able to do both thanks to the low volume. There is a very loud electric blues jam once a month in the Shamrock, and I enjoyed this session far more, the lower volume being a major factor. I'll probably go again, and might take along the mandolin and/or the Weissenborn to give a bit of variation to the sound.
