Close enough to take a picture = close enough to reach for a screwdriver.

The same but fatter or bigger? Like the Rockster boost on the TW forum that might just be a parallel gain stage.

Get the tools out. You won't be able to tell by the circuit (lol) but you will be able to see what goop glob the wires run to next. :D

Yeah, if that pic is yours, crack it open. This is a technical forum after all ;) I looked at some other pics of the 5-tube Tippers, and it looks like the extra tube comes after the first two typical BF stages (first stage, and tonestack recovery stage), but before all the reverb and reverb recovery/mixer stages.
So there's something going on after the tonestack, but don't know what. I couldn't really tell from the pic if both triodes we being used.

Does the 5-tubes version have more gain at all?

a friend that is an ampbuilder with a cowtipper reports that the extra preamp tubes simply emulates the normal channel. the vibrate/reverb channel and the extra tube are connected with standard fender 220k mixer resistors. the extra tube is not really used for a normal channel like fender did. but bruno must have feelt that the normal channel affects the vibrato channel. Therefore he added an extra tube and the 220k mixer resistors. the extra tube had a 1m grid resistor first, something that was later replaced with a 33k resistor (or so I'm told)

it causes subtle compression because of the shared cathode-resistor and the "220k-mixer-loading" also differs slightly.

Not sure but it obviously works as it sounds better than the older model without the tube. Whatever it does, its sure not a SR clone.


I cant pull it apart. Its one of 3 Brunos I sold to help fund 183. May have another one soon, but it depends how the deal works out. Still doubt its mine? Scott Lerner played through it at my house. Ask him what he thought of the tone. :wink: Again, if I score this 35 or 22, I will open it up and post pics. The guys who listen with their eyes will REALLY love it! :lol:

Well,
The used deal kind of fell through, so back to the city and then Ultrasound to play everything I could find. After 2 hours with Gene and many Bruno combinations and configurations, I could not leave without this guy.

[IMG:483:400]http://pic50.picturetrail.com/VOL438/64 ... 834592.jpg[/img]

A brand new Cowtipper 35 ProII and 1/2. :wink: Tony has made a few more changes to the basic Cowtipper 35 Pro 2. I played them all side by side and with different speakers and cabs. Surprisingly I ended up with a 1/12 combo with a Heritage G1265 speaker. I always like the G12H30s the most for cleans, but with this amp, in this cab, it was the best for what i like. I also tried Cowtipper 45s and 22s and a tweedy pie 35 all into an oval ported 2/12 with heritage 65s and a semi open back 2/12 with G12H30s. Again, the combo cab sounded the best to me. HUGE dispersal of sound!
Here is the deal on the schematic. It could be 100% correct for THAT order. (It may have been a brand new one, just what the guy wanted.) Tony makes each one exactly how the person wants it. Some guys want a dead on clone of a fender, others want a bit more bottom, or a bit more top end, more VOXY on the high end, or whatever. There are even several ways he wires up the reverb. The additional preamp tube is the way Tony likes to "load" the circuit the most to HIS ear and comes with the basic model. You can yank the tube, and get a more "traditional" Fender, or older Cowtipper tone. (I tried this, and probably will leave it out for my archtop playing) He also offers other ways to do this, but the tube version is his favorite. i have owned and played many Cowtippers, and this particular model is my favorite yet. I played several vintage fenders at GC and other dealers before hand to adjust my ear, as its been a while since I owned one. Like back then, to my ear, the basic Cowtippers are sonic improvements in every way. Its great to have another one after all these years. Dumble overdrive and bruno cleans and semi break up tones. For me, thats as good as it gets. :)

Bluesbreaker cloth looks great on that amp. Using that on my newest ones. Glad you found one you liked.

I don't know Tony at all, but if he can take a circuit he likes and tweak it to a customer's taste, more power to him. That's marketing, not design, and I am first and foremost a marketing guy so I appreciate it.

Thanks. I am really excited about having another, although in this economy, by the time I pay it off (credit card purchase) it will probably cost me as much as my Dumble did. :( Looking at the Bruno website, the Cowtippers are advertised as blackface tone tweaked to perfection. It seems they are exactly what they are advertised as. Tony does not say they are his original designs. The tweedy pie 35s are basically 56 bassmans with a few tweaks. Nothing is being stated otherwise. The UG 30 is his baby from what I understand, and I have never heard anything else that sounds like them. He also has some other amps that are very unique. Another thing I can say is that throughout his line, and he makes many different types of amps, is they all have a "bruno" sound to them. No harsh tones, and very musical. The notes always seem to blend in a musical way. Clean inside or not, the guy makes killer sounding amps that hold up extremely well. Nice to have his amps available as a choice to all of us players!

Firestorm are you using the EC Collins crazy-expensive clone cloth or something close?

Yeah, I totally agree with your comment about marketing. Marketing and product are two separate things and being successful at business is more than just having a great product.

Tag, nice acquisition. I do like that Hollowbody! That guitar sounds killer on your Paperback Writer cut.

Thanks! That was my Tele on the PB writer clip however. A Nocaster that I dropped a set of Mare pups in. I always kind of dug Lollars, but took a chance on the Mares. I am glad I did as I love them!

I don't think the cloth was stupidly expensive. Something Taylor Cox uses. He also had this great marine tolex that looks like carbon fiber. I was going to wait until I had the prototypes built before I posted pictures, but let me go to the other computer and find a pic.

Yeah, not the crazy expensive stuff, (sort of Bluesbreakerish), but not bad, right? I think Taylor did a killer job.
