Bogner Goldfinger 54 Phi Head
“A Chameleon tone stack and small footprint with power from 9 to 66 watts of clean headroom bring you mobility and flexibility”
‘The 54 Phi is another killer amp. What I really love though is it’s got a killer clean tone and then killer dirty tones all the way through to chunky rock. There isn’t enough space to describe the tonal capabilities and features in any detail, you really need to try the Phi 54 for yourself as there’s so much tonal goodness under the hood. Harmonically rich for cleans and dirty tones, they really are gigging tone monsters capable of sounding juicy and big at usable volume levels”

Big bass with shimmering high cleans
The Bogner Goldfinger 54 Phi Head features a front end is vaguely based on the Goldfinger 45’s pre-amp but with the ability to change it’s tonal character via the BAX mode from a classic 60’s tone stack to a Bax EQ which is reminiscent of 50’s department store amps. BAX EQ engaged takes away the big bass with shimmering high cleans to a pure balanced even EQ spectrum that is unique, articulate and vintage in style.
Two Boost stages
Two individual boost circuits let you either add more preamp push, a trim pot helps dialing in your personal preferred level, or a fatter tone with singing mids for solos with a more overall British voiced tone, both accessible via the foot controller.
Phi also includes lush spring reverb and a tube buffered effects loop. A single 16 and selectable dual 8 or 4 ohm speaker outputs as well as an adjustable flat frequency Line Out for routing IR speaker simulation software or running post effects for stereo bi-amping setups.
Dual 6V6’s and 6L6’s in the power amp
The flexible tube array with two 6V6’s plus two 6L6’s combined as well as the option to mute either pair and run it on high or low power setting via the three position Standby switch makes the Goldfinger 54 Phi a multitude of different single channel amplifiers in one. It can be a 66, 58, 33, 27, 19 or 9 watt amplifier each with a different feel, compression and volume. The head version with a 17 by 9.5 inch footprint at a height of only 8.25 inch is among the very smallest all tube 66 watt amplifiers on the market and consider all the features and you will find no competition left.
The Golden Ratio
The Greek letter Phi Φ is used as symbol for the Golden Ratio.
“Two quantities are in the Golden ration if their ratio is the same as the ratio of their sum to the larger of the two quantities”
