Webb amp with a Sica speaker. Too much highs.

Post by Dale McPherson »

I recently acquired a Webb amp with a Sica speaker in it and I can't tame the highs. Way to shrill for me. I know I have all the makings of highs using a 710 pickup, George L cables and a Telonics pedal but I can cut them with my Peavey Session 115 and my Telonics Amp. So, can any you Webb owners offer help?

Webb's are made for JBL K130's or E130's. I've tried others but always come back to one of these two.

Me too pretty much....although the Altec 418B works well also.

Web amp with a Sica speake , too many highs.

Post by George Kimery »

Just went through the same thing with an Evans pre-amp. Solved the problem with a Sarno Back Box using the
Variable Z control. Brad also makes a clip on the leg
tone control called the Freeloader, which is an integral part of the Black Box. You just wouldn't get the advantage of a tube buffer without the Black Box. You can also make up a special "Webb only" cord with a 500 K resistor soldered into it to reduce the highs.

I was running a TT-12 speaker, but just got a pair of GD Walker cabinets with 15" JBL-D130's. Definite!y not as bright as the TT, but it's not a fair comparison since the TT is 12" in an open back cabinet and the JBL's are 15" in a closed back cabinet.

You can also try a beam blocker to cover the center of the speaker.

They make them out of steel but a DIY circle of foam can also help and some like the foam idea better than the steel units.

Experiment with thicknesses and densities.

Perhaps a 6 or 7 band eq unit can solve your problem.

Interesting that you get too many highs with the Sica speaker. I had one that I sold for the opposite reason. In all fairness, I might not have given it enough break in time. Your Webb should have a five band Equalizer section. Some players don't use it, but I find it helpful in tweaking for different rooms. Try experimenting with it. Start by turning down the highs using the knob farthest to the right. It took me a while to get used the the EQ section in mine, but like I said, it can come in handy.

If you have the 250 watt Sica it's like a 1501-4 BW.....the 300 watt Sica is like a 1502-4 BW..that might be what you need to cut the highs.

I have found that the selector switch in the middle position and using the EQ section as well, helps the situation. I think if I had a Sho Bud guitar, it would be an awesome combination. But both of my Show Pros have a 710 pup and they are naturally bright. A Izzy might help but I will never use the Webb anywhere except at home. Too heavy even with the lite speaker.

Dale, you need to borrow my "Freeloader" I believe that would help.

Actually, I was just on the website reading about one. I may order one and try it.
