Just seeking information in this small servey:
Where do you set the Sensivity control on your Webb amp. (ex. with an Emmons single coil pickup)?
And:
I play the Fender 1000 through the Webb amp. also. On the 1000, I get the best sound using the #3 position on the Selector switch. Is there a rule of thumb for setting the Sensitvity control using the thinly-wound Fender pickup through the Webb amp, excluding, the "whatever sound best" standard reply?
Many thanks, Rick[This message was edited by Rick Collins on 26 January 2004 at 08:59 AM.] [This message was edited by Rick Collins on 26 January 2004 at 09:00 AM.] [This message was edited by Rick Collins on 26 January 2004 at 09:01 AM.] |

Mr. Webb told me that the sensitivity should be full on. It's to be treated as an attenuator in case you have a very hot input. For a passive steel guitar pickup you would be safe with it cranked. However I've noticed that if you bring down the sensitivity and compensate with more master volume, that you get a brighter tone, thinner. The sensitivity full on gives a meatier, warmer tone. The hotter the sensitivity, the harder you drive the FETs and the more tube-like tone you're likely to get. No rules other than what pleases your ears the most.

| Right on Brad Sarno. I do keep mine on ten as Mr. Webb suggests. |

Interesting... I always run mine on 6. No particular reason, except that less always sounded wimpy. I never thought of running it on 10. I just turned it up until it sounded good.

Thanks for the info Brad Sarno and Bobby Lee! I read this and immediately checked out my Webb sensitivity setting and what do you know, it was set at 3! Yikes!! My Webb was sounding a bit thin in my recent amp comparisons. I had always thought that being well into the safe zone was a good thing much like with a microphone preamp. That transient peaks would be treated like the average signal. I, perhaps incorrectly, thought sensitivity was for achieveng best signal to noise, not driving FETs. My amp is really quiet with sensitivity at 3 and volume at 4, so I'm thinking... better safe than distorted. Now that I think about it, rounding the peaks off might be a huge plus for PSG, especially the third string. I am going right now to do a comparison. OK, I'm back from listening. A difference is there but subtle. It seems in all three tone selector positions that the mids come up a bit when sensitivity is at 3 and the volume is raised to level match as compared to sensitivity at 10.
Also, note separation is a bit better with the sensitivity on 10. I was careful to try to do an same level comparison. It is very hard to level match and if you don't you can get fooled easily, most of us will interperet louder as better (less wimpy).
I also tried the master gain to volume comparison with an Evans FET 500 LV small cabinet. In an Evans, the volume is for preventing distortion and the master is like the volume on a Webb for the level you'd like. Tons of distortion with the volume at 10 and master gain down. Also, with the Evans, the two seem to be for mimimizing hiss and staying below distortion.
The forum is great for many things including exactly this type of thing.

| I've been running mine on #8. The only reason is. . . .I just got the Webb about (3) weeks ago and I put it to same settings Rusty Danmyer uses on his. We play the same gig on Saturday Nights so I looked at how he has his set. Nick |
