Oh man do I need help.
Im trying to eq a new (to me) aguilar gs 212 paired with my quad 6 .
At the moment im getting only mud q3/4 or glassy thin tones q 1/2.
I cant seem to find a happy medium, others have suggested a outboard pre like a tonehammer or sansamp, but i believe in this case its user error. Previously Ive only used very simple EQs.
My research leads me to think that you can dial almost any tone you want. I just dont know how.
Can you tell me what your basic settings are and a little bit about what you think the "philosophy" of how this pre is voiced and is meant to work.
Thanks a lot!
The Quad is by no means a simple beast. Each of the presents has it's own EQ curve. It is definitely a warm\bassy amp with everything set flat but I can definitely get some grindy\bright tones out of it. Above ive attached a screenshot that shows the default EQ of each Quad preset and also the affect of each EQ knob (I hope it's readable, I'm typing this out on my cell phone in my lunch break ). My take is this...
Preset 1 - typical mid scoop EQ. Sounds nice and smooth but not my cup of tea.
Preset 2 - close to flat response EQ wise. Not a bad place to start on this amp.
Preset 3 - this preset has a low end roll off that starts around 200hz and starts to get steeper down around 100hz. Odd that you find this preset muddy because of this roll off. This is my favourite preset as you can generally add the bass in that you need. It also has quite a boost in high treble, but to be honest it's in a frequency zone that most bass speakers won't reproduce.
Preset 4 - I call this preset the "Ampeg with Ultra Hi and Ultra Low buttons pushed in". Reminds me too of Sansamp BDDI tone, it's very bassy and trebly by default and can be EQ'd for a really good metal tone, but I dare say that's not what you're after.
From there, here's my take on the knobs in a general sense;
Bass button - large boost around 40-600hz
Bass knob - boost\cut at around 80-90kz
Mid 1 - boost\cut at around 200hz
Mid 1 shift - boost\cut around 450hz
Mid 2 - boost\cut at around 600hz
Mid 2 shift - boost\cut at around 2khz
Treble knob - broad boost\cut at between 5 and 10khz
Treble button - large boost at very high treble frequencies
FWIW I rarely use P1 or OR, and never use the bass or treble buttons, but I do get diverse tones from P2 abd P3 in combination with the EQ. Use the frequencies above as a very general rule and just gave a play to find the tone you're after maybe? Gotta head back to work but hit me up for anything else you want to run by me yeah?
