"Used by top pros! A shortcut to real Plexi Marshall" The Helios100 is a 100W model with a truly good-looking design that even surpasses the original Plexi head. And just looking at it, expectations reach their peak—it's the original "modified Marshall." HELIOS, the album that Bogner, with his signature sound image, has finally released! The "70/80" VOICING SW on the front panel of the 100W Helios model is precisely that sound switching switch; in "70" mode, you can enjoy a fat and dynamic overdrive sound. A fantastic tone reminiscent of late 70s JMPs, complete with a master volume control. "80" has a pleasant, slightly compressed feel, full of 80s vibes, like an EVH-tuned distortion! By turning on the EQ bypass switch on the front panel, you can enjoy a direct and raw tube tone. This produces a dynamic tone that truly brings out the full potential of the guitar, much like a vintage tweed Fender. This is a must-see for players seeking the ultimate Plexi sound![Helios 100]・Point to point hand wired two channel all tube design • Plexi and Hot gain inputs・Ch1: volume control and 3 position bright switch・Ch2: gain, bass, middle, treble and volume control・Pre Eq switch for plexi bright, normal and bright・70's or 80's voicing switch・EQ bypass switch for raw pre - power amp voicing Common spray control・Bottom controls with punch switch for low end response・Tube buffered series effects loop with return level control・JMP-100W or JTM-30W mode switch (100W model only)・Functions on foot controller: channel select and effects loop・Classis traditional Amp head cosmetics (no grill cloth) Comet tolex 27.3(H) x 73.7(W) x 21(D) cm Weight: 20kg
