On the Foundation, unless the mod you did to it changed the way it works, put it in humbucking mode by dimming both volume knobs and see if that makes a difference.
That was definitely true for the Four Seasons and Gibson. And Mosrite with the Ventures for a few years.
VBT, so I’ll trying full up on the single volume knob.
The Willbird sounds fantastic through the B-15. That’s the sound.
Most definitely went on. The Beatles were sent gear from Fender leading to Paul briefly using a lefty J in the later '60s for recording. There was also George Harrison's rosewood Tele seen being played on the "Get Back" roof performance made by Phil Kubicki when he was employed at Fender under Roger Rossmeisl. There's a thick Beatles gear book that lists all the gear they used and when. George is pictured playing a Burns bass. Gibson & Epi guitars appeared but no Thunderbirds were involved...
It's the same with the variety of fret-less to fretted bass designs over the years. Much fussing over instead of simply having one of each.
Congrats! - you should post on the Ampeg Portaflex thread -
There were two 6L6GC power tubes in my 1966 Fender Bassman and it put out 50-watts rms. I'd normally "expect" 25-watts of power from each 6L6GC tube unless the designer wired it differently. so two of those would normally be 50-watts and 4 of them for 100-watts. So my guess would be 50-watts. Ampeg could certainly be different than that though.
And plays that way as well.
My B-15NC is 25W.
Dave, don’t quote me (I’m no amp expert) but IIRC the B18 had about twice the wattage rating of the B15. So somewhere around 50/60watts I think. It gets PLENTY loud in my home setting and I suspect would even handle a medium size bar or small outdoor gig.
22 Watt….Bassmans are Class A/B (efficiencies of up to 66%) your B-15 is true Cllass A with a max theoretical output efficiency of about 35%…
those are called “Getter” flashes…..when they are done exhausting the glass envelope with ambient gas (air) they momentarily (seconds) burn thoriated tungsten (by impressing a voltage on the ring in the below pic) which will trap whatever oxidizing (oxygen) particles are left in the glass case after the vacuum pump onto the glass. The tighter the vacuum the more rugged the structure and hence higher break up conditions…..euro tubes are reputed to have softer vacuum and are well suited for guitar amps……getter flashes can be seen in different parts of the glass case, manufacturer and tube type…..7027s typically have them on the sides and (as can be clearly seen on both, your and my pics) on top…,,
You do realize this group is sponsored by the Bass Gear Sales Improvement Association?
S&M[1] Will always round up.
