- Page 2 • • • Tip: For maximum clean headroom, set the Loudness control (see below) fully-clockwise, and turn up Gain I to desired level of 'cleanliness' with your particular guitar (usually below 12 o'clock). Tip: Experimenting with the balance of Gain II and the Level control can produce different overdriven textures.
- Page 3 Note: You may notice a slight lag in response or spurious noises when turning the Loudness control quickly. This is normal, and is the amp 'readjusting' to the new voltage conditions. You may also notice that the physical 'feel' of the Loudness control is different when turned. This is also normal, and because the circuit necessitates a special high voltage potentiometer which has a slightly different torque when rotated.
- Page 4 Note: Speakers must be rated for at least the full rated clean output power of the amplifier (30W). Under overdrive conditions, the power of the Shiv can be up to 45W, therefore it is preferable to use speakers whose combine power rating exceeds the clean power rating. This topic is up for debate as some speaker manufacturers rate their speakers with this knowledge in mind (i.e.
- Page 5 • • Tip: With the amplifier on and the rear panel removed, you may be able to identify a microphonic tube by gently tapping on each tube with a pencil's eraser (for example, since anything hard may potentially crack a hot tube) to see if the sound becomes worse or changes. All tubes will amplify the sound a little, especially preamp tubes.
- Page 6 Note: V4 and V5 are one pair and V6 and V7 are the other pair. Tip: Buy “burned-in” tubes when possible for maximum stability and minimal bias drift.
