Congratulations!

A rule of thumb that applies across most 'durable' goods is that once they show any signs of use the value drops to about 60% of new. You might get more for immaculate with-box items, most most buyers willing to pay, say, 80% of new value for a perfect example will usually consider going tehe xtra mile and buying new to get a warranty etc. It's very easy to assume that because I paid X for this and it's 'still as good as when I got it' that it should retain most of its original value. Obviously these rules don't apply where scarcity/collectability is a genuine factor. Also worth bearing in mind that (a) 'there's one born every minute' applies to buyers and sellers and (b) the secret to selling for a good price or buying a bargain is patience and willpower (plus a little luck).

I should have kept them in a bag.

Listen to some funk and learn some nice syncopated rhythms, that's what I'm doing at the moment 🙂

That's how I read it, the Beta 12 likes a decent sized cab. At 45 litres the curve is a lot flatter At 200L you can tune it get way down past 40Hz, about -6dB @31Hz . Win ISD is a fun toy...

I want 'em back!

I think the secret is that this gain control circuit doe not have a liner frequency response. As VR1 is increased the amount of negative feedback, reducing gain. C1 means that the treble will drop off faster than the bass with the effect that the sound will be less 'lively' at lower gains. No component values and I'm not familiar with the details but that's what I think is going down! I would be interested what someone with more knowledge of audio amp design has to say:

That's a bad contact at the connector/wire you are wiggling.

I've been emasculated!

I have donned sackcloth and ashes and will flog myself daily for a year and a day.

Oh dear, my maracas have gone missing!

20 volts peak to peak is the maximum signal without distortion you can put into the Ashdown's line in - that's plenty of headroom so you should have no problems. You would use a guitar (signal) lead. An earth loop is when two amplifiers share the same earth (via their mains plugs) and then have their earths connected together by the shield on a signal cable. This creates an induction loop that picks up mains hum (like a single turn of a massive transformer). If you cut the earth(shield) inside one jack plug you break the loop and get rid of the hum. NEVER break the loop by removing the earth from a mains connection.

My 9th birthday acquits itself quite well too. Voodoo Chile at number 1 and James Brown's Sex Machine at No 50, with Paranoid and Black Night in between.

I heard a song I hadn't heard before on the radio, I thought 's**t that's good' and got google to identify it. "You can't get away" by Mountain. Methinks its about time I bought a copy of Nantuncket Sleigh Ride. (album) On the bright side, we obviously have a lot to look forward to...

It did! I'd link to my post under the gig last night thread but I can't find how to link a specific posting, so: We were the 'Grizzly Beers' and on second. The sound was spot on as you might expect from a venue with a proper stage and a list of past bands like this: Were were hoping not to make fools of our selves but in the end we had a great reception and everyone was saying how good we were, especially how we fitted all the instruments together. We started with Going Back Home as easy to play and a crowd pleaser. The Saturday Night's Alright for Fighting which is a tad more challenging! Our secret weapon was Boulevard of Broken dreams where we got all those stops spot on, including the end - our effort to practice endings really paid off. We did 40 minutes and finished with My My, Hey Hey. I started it with my HM2 pedal dialled and a plaintive howl of feedback, calmed down a bit for most of the song, and finished with HM2, tremelo, flanger, EQ and chorus on and the compressor off! The plan was to go out with a bang and it turned out we managed to make a picture fall off the wall at the far end of the building in the next room 🙂 We ended witha group hug! A few moments of sheer terror, but in the end we all had a brilliant time and the other bands were great too! We are meeting up in a couple of weeks top discuss a plan for world domination!

Not a mates of Rrussel is he? Looking at the PJ it has line out on the back and the Ashdown has a line in that will take up to 20V P-P, so all you need is a jack lead from line out on the PJ to line in on the Ashdown. If this causes hum, you might need to break the earth connection at one end of the jack lead to break an earth loop* (and mark it so you know why it doesn't work as a normal lead anymore). *unless the Ashdown has an earth lift, which I doubt.

Yes the mains plug should be providing your earth. I'd be surprised (horrified) if something metal cased like that was unearthed. Can you describe exactly what causes the crackle, is it jiggling the connector in its socket (plug or socket likely to be worn or dirty) or jiggling the cable where it goes into the connector (damaged conductor in cable). Does the hum depend on where the microphone is held? Does it get worse when near a mains powered object? does it get better or worse if you touch the microphone windshield? If the cable is not mating properly with the connector in the microphone or has a broken conductor that could explain both crackles and intermittent hum. The last rehearsal we had two out of three cables crackled really badly when plugged into a mike, one was even cutting out completely. A third cable was fine. They all looked pretty new.

It's the 'Playboy' version... (think about it). Actually the umlaut appears to be an optional extra...

You need to learn your hat etiquette. It is customary for a man to remove his hat when indoors as it is worn as an item of utility. A woman wears a hat as part of her outfit, so may keep it on indoors. However, once performing the hat is part of the stage outfit and may be worn indoors.

Those ground terminals are for building it into a permanant installation when you want to avoid earth loops and have everything grounded from the same point. It shoudl be grounded through the plug. If you get crackles from moving the XLR plug in its socket and humming when the mike is plugged in this suggests the XLR plug is worn OR there may be a wiring fault in the lead.

Here it is in WinISD, assuming 30l cab tuned to 56Hz (two 64mm ports 160mm long) and 150W. The Beyma is the green line, the bottom line is an MCM 55-2982 a budget-ish driver available from CPC for about £50. The red line is an Eminence Beta 12. From these three the Beyma is probably going to have the best balance of top and bottom end. That resonance for the eminence might make it boomy.
