Ampeg SVT 7 Pro Club

Interesting. I'll consider buying and trying another of the original fan if I plan to take it into the heat. As for at home practice, the concerns I had with these PC fans greatly diminished once I opened the amp right after playing and was shocked how cool everything was.
The overall impression of “coolness” is misleading, there are a number of specific components (different components in different designs) that are heat sensitive, which dictate the requirements for airflow (CFM, static pressure and direction).

When designing a (reliable) cooling system, thermal sensors are placed at multiple critical components to be sure they all track together.

Additionally, in some designs, there are also multiple sensors at key components that feed back temperature information to protection circuits. When these are used, it’s important that the cooling system doesn’t over or under-cool the sensors or protection circuits mistaking can occur (with disastrous results).

This is all part of a patent we were granted about 15 years ago relating to SMPS and class D cooling and duty cycle management.

Buzzzzzz

Sometimes this happens. My dingwall and my Stingray 5 are both generally dead quiet. But the Dingwall can be susceptible to powerline noise from cheap dimmers, and the Stingray 5 is not. There's one venue in town (playing there in two weeks actually) that has such bad powerline noise that I can't use the Dingwall. It's the only place around where I have that problem. Unfortunately for that kind of noise there's not much you can do, especially if it comes from cheap dimmers. Just bring a bass that you know is resistant to it, as your Sadowsky seems to be.

Sometimes the bass gear isn't what matters.

It's not the PA (though that helps)... it's the guy running it.

One local venue has a reputation for bad sound. Some say it's the equipment, some say it's the shape of the room (definitely not ideal). I saw a semi-name band there a few years ago. For the support band the sound was its usual mess. After they'd finished as the headline band were setting up, their touring sound guy (who looked like the bad guy from Prison Break if anyone remembers that!) stepped in, and kicked the house guy off the mixer. He pulled up the settings he'd dialled in at soundcheck, the band kicked in and sounded AMAZING. I watched the sound guy make a few tweaks during the first few songs and it just got better. The sound was cohesive but I could hear every instrument standing out perfectly. The house guy (who was shadowing him) was just owned, and I made a point of telling the touring engineer how much better it was, within earshot of the house guy! The band were pretty bad, but the sound was some of the best I've heard from a PA that had a reputation for being the worst in town. I just kept hoping the house guy was smart enough to snapshot those settings...

If the sound guy is good, then they'll make you sound good. If the PA is good, you'll sound as good as the sound guy makes you!
This, 100%.

About a month ago, I had a comment from FoH guy that the bass was too thin. Same Ray35 bass, same player, same FoH rig in the same large church. The difference was a much less skilled volunteer FoH engineer.

Quad Cortex - Neural DSP

Is anyone running their QC into a pa style power amp? I'm wondering how it fares with an amp that needs 0.775V? My QC is set now for normal mixing desk and instrument input on amps type levels, is it going to mess up all my presets if I want to sometimes run into a power amp instead of a normal bass amp? Am I better having a separate rack preamp? (Which I might do anyway for stage sound control).

Ampeg V4B into SWR 8x8

Just to be clear, you had 2 700 into 2 Henry cabs or do you mean 2 700's into one cab. How did you do that?
I used either 1 x Henry w/ 1 x GK 700rbii or 2 x Henry w/ 2 x GK 700rbii.

Used 1 when the guitarists used a half stack each with 120 to 150 watt tube heads and used two when they each used their 612’s.

What the absolute least amount of pedals you could get by with?

I could probably get by with an overdrive and a DI. But, the absolute least that I could use AND still be really happy with the tone....2 drive stages and a preamp. Others that make an appearance are compression, octave, fuzz and chorus.
Right now, a small board is too small and a big board is too big. So, I have space to work with. Sometimes I fill it, sometimes I have a lot of empty space.

Eminence Delta 10a-2

Using the program fdeck provided, these drivers look good in a small enclosure like the rumble 500 combo. Pretty flat down to around 50hz, tuning was about 58hz, total internal volume 2.6cuft. These are rough numbers from memory. A pair will handle a solid 270 watts. I’m not a fan of how the menus have changed on the eminence site. It’s harder to find what you’re looking for. The previous version was excellent.

Another Rotosound 77 break-in inconsistency thread

Good news: a bit of lotion settles down the strings nice and even. Is that one of JimmyM's words of wisdom?
This is one of the reasons why I like the Fender 9050L (45-60-80-100) better than the Chromes ECB81 (45-65-80-100).
This is a good tension, I wonder why more companies don't make it. From my calculation, a balanced tension set (assuming uniform density) should be 40-52-70-95 or 45-60-80-105. Strings with different core-to-wire ratios would have different densities, so maybe a high-density 50D or a low-density 55D will work well with a medium-density 40G.

Still hunting for gray Ampeg cloth!

I didn’t see any mention of the Fliptops store, so I’ll just put it out there.

Fliptops Home of Parts for Ampeg Lovers

Edit: I do see now the 1st post made reference, from JimmyM.
Yeah, Fliptops is an incredible resource but unfortunately they don’t have anything like what I’m looking for.

They don’t even have the current production blue sparkle at the moment. My game plan was to get a couple sample squares of that (so as not to mess up my existing grills) and try some methods to dye it, probably with coffee and tea. If anyone here has a roll and could cut me a few squares I would be grateful!

The project has kind of been on hold because of these dead ends. Best I can tell, somebody at one point definitely made a more gray version of the cloth with the classic weave pattern - somewhere between the 90s and 2010s - but it is almost certainly out of production now.

Double Bass String choice for low bow pressure

Update: I tried Spirocore Solo 4/4 E (F#) & A (B), Evah Pirazzi Slap E & A. Also Flexocor Deluxe Solo E (F#) & A (B). With the Spiros and Flexocor, I can't find a soundpost placement that allows E & A to speak quick enough without D & G sounding too harsh. On the EP-S it worked. On a side note, they tend to bottom out fairly quick when busking acoustic pizzicato.
Anyway, i am back to plain gut A/D/G. I'm in love with Dragonetti's 12 waltzes ever since i took up the bow. They work wonderful with plain gut strings. I just can't get used to the difference in attack (slow, no "chaff") and timbre between non-gut A and gut D+G. Somehow, Steel E doesn't bother me (at least when playing Dragonetti, you don't use it anyway :D)
