But gradually guitarists began to expect more from an amp. Increasingly dissatisfied with the limited sonic spectrum of these one-sound wonders, players started toting an array of amps into the studio. And soon gigging rigs followed suit, growing more complex and difficult to manage. Players’ desire for more options sparked our vision of a new generation of guitar amps for a new generation of guitarists. We aspired to engineer advanced sound-sculpting tools that would unite the best of the dispa

• Did the Mains voltage fluctuate or spike while the amp was on? In all-tube amps, over-voltage surges in the Mains net can certainly cause drop-outs. Over-voltages are often caused by generators and faulty high-current power circuits. • Perhaps a fuse blew even though none of the tubes is actually defective? An old fuse, tube de-ionization or Mains voltage power surges may have triggered the fuse. Things to Bear in Mind When Replacing Tubes Replacing tubes is a job best left to qualified profes

With the marvelous new Statesman series, Hughes & Kettner has debunked the myth that all classic tube amp designs lack versatility. The Statesman models’ kinship with ‘60s-era forebears is obvious at first glance – they share that familiar look & feel. Sporting 12AX7 preamp tubes and EL 84 power amp tubes, they would also appear to share the same DNA. Take a closer look, though, and you will see its talents transcend mere mimicry, with two sweet-sounding discrete channels! Clean delivers the sou

The amp’s full output power of 400 watts at 4 ohms (250 watts at 8 ohms for the QC 310) is routed to this port. This means you can connect external speakers with a total impedance no lower than 4 ohms (8 ohms for the QC 310) to it. 5.8 Standard Setup / Cable Connections Quantum TM-combo Manual 6. Service and Maintenance Quantum amps do not require service of any type. There are however a few basic rules that – if you follow them - are sure to extend the service life of your amp enormously: • Mak

Frequencies lying above the TREBLE control range’s center frequency are dampened, which emphasizes the character of this voicing control. Pushing the PUNCH button clearly enhances the HF-CHARACTER knob’s effect. The illustration shows the curves for PRESENCE (top curve) and TREBLE (bottom curve) at extreme HF-CHARACTER knob settings.
