The 6505+ is a second version of the 6505 and is identical to the 5150II. It features an extra 12AX7 tube in the preampstage, to prevent breakup in the clean channel. It features separate 3-band EQ, presence and resonance controls for the 2 channels. It also features only one input, unlike the 6505,

The amplifier has two channels, rhythm and lead. Each channel provides the user with separate pre-/postgain control, and the rhythm has an extra crunch and bright switch. The channels share a 3-Band EQ and presence and resonance controls. Switching channels can be done both via the front panel of the

Although some players believe that the 5150 (particularly the "block letter 5150") to be better-sounding than the 6505, the only difference is that the original 5150s shipped with a different brand of power tubes. Since vacuum tubes are consumable items, it is likely that the original power tubes

Design of the amplifier began in 1990 and it became a flagship project for Peavey and for then lead engineer James Brown (who has since founded
Amptweaker), lasting for about 13 years, comprising the 5150 and 5150 II, until 2004. Peavey has since released several other versions of this amplifier.

A defining attribute largely responsible for the 5150 sound is the fixed bias. Commonly described as an analog to a car engine and its respective idle, the 5150 bias was set to a lower value (lower engine "idle") which resulted in the Power Tubes running at a lower energy commonly known as

Initially, the Peavey 5150 I shipped with four
Sylvania 6L6 Power Tubes; this was later changed to Ruby Tube 6L6 Power Tubes, when Peavey's Sylvania supply was exhausted (per James Brown, "Tone-Talk", Ep. 17), and five 12AX7 Tubes in the preamplifier staging (with one as a phase inverter).

It is available in a 60 watt 1x12 combo (Called 6505+112), of which the internal circuitry is similar to the head, but with 5 tubes in the preamplifier, using 2 instead of 4 6L6GC powertubes an additional 3-spring reverb. It is made in China to cut costs.
