"Have you tried switching it off then on again?" Seriously, I am glad you have got it sorted.

Because a user cannot know what effect she/he is having on the cabinet characteristics. Also, there are many things we did 50 years ago that we do not and would not do now. Indeed, Child labour in the UK was only really banned in 1944 when compulsory state education was introduced.

This is probably better described by@agedhorse earlier but... To get maximum voltage transfer, the input impedance of the amp should be at least ten times the output impedance of the preamp. A bass head will traditionally in the region of 1 Meg ohm or one million ohms. In that case, the 12K output impedance of the Sadowsky is fine. As it is, you are losing approx 1/2 the voltage output by your preamp due to the low input impedance of the Sumo. You could connect half the balanced DI output on the XLR. Although you would lose half the output, -6dB, you would regain it due to the lower impedance and if we assume that the DI output is at line level, it will be much higher. This assumes that the DI output is at a professional line level, 0-4dB.

Of course, some bass cabinets are flat and have a full and have flat frequency response or transfer function, ideal for either modelled sounds or the traditional Head/Cab use. However, even those will sound different due to both the specifications of the drivers used and the design goals of the designer(s).

Bill is correct, but of course some "tops" with DSP have a monitor setting or even provide a high impedance input suggesting that guitar/bass is allowed or even expected, but a "top" capable of handling a bass at volume, without a High Pass Filter is both expensive and rare. I would use your Ampeg Pre-Amp pedal into a lightweight (compared to your EBS) head into a good cabinet. I am not going to recommend any particular amp or cab, but the main difference between amps is the Pre-Amp. As you have the Ampeg, look for an amp with a good power output with the ability to bypass the front end and input to directly to the power amplifier. As for cabinet, look for n uncoloured cab (the colour is in the Pre-Amp). The main thing about a PA top, such as the QSC 12.2 is that it has a decent crossover, compression driver and horn. Very few bass cabinets have this, so even those with tweeters are a significant compromise. Also avoid cabinets with adjustable tweeter level. This suggests a lack of confidence in the design. Your bass and preamp can reduce the treble, so why put an attenuator on the cabinet?

Not had any problems, have you asked on the A&H forum?

You do not say what the new speaker is, but I suspect it will go very low but is very inefficient. The rubberised surround suggests big Xmax, low efficiency. Without modelling it, the results may not be as expected and as experienced designers will tell you, modelling really only gets you 90% of the way there and if the cabinet is tuned incorrectly, that 45 watt rating may be too optimistic.

You have to define PC. To the Orange one and his glove puppet JD Chancer it is anything that stops them being an asshole, them doing or saying what they want. Woke is anyone that disagrees with them.

What Tuner are you using?

Drives me crazy whenever I go to the US. At least VAT is already on the price over here, you pay the price you see.

There were using a secure system, but not as secure as it should have been. It is a commercial service, ironically like Hillary Clinton's use of a private email server. If a "secure" service is in public use, you have to accept that it can be, and has been, hacked. In this case, the people involved (except the journalist) are stupid or ideologically blind, which in many ways is worse. These people are in charge of the world's largest nuclear arsenal. Something that tempers Putin's behaviour but not the current Trump led destructors.

Are you using the asio4all driver?

I think this is how I got my current place. However, the rhythm guitarist's health is deteriorating, but he won't admit it is time for him to hang up his Strat. If nothing happens soon, and the BL has been told in no uncertain terms, I will be on JMB, and they will be looking, probably in vain, for a new bassist.

I honestly don't have a problem with the volume control, yes it can be a bit noisy, but it is not that objectionable.

Me too, when my MacBook Pro died after 12 years faithful service, I could not afford to replace it and bought a Windows device. In all matters audio as well as most other things, the Mac was superior. WTF are drivers? The hiccups come with the dominance of MS Office, although Open Office or LibreOffice can do 90% of what the MS Office Suite can do. Anyway, I am saving for a new MacBook.
